Hi all, i remember reading somewhere here that one workshop can change spark plugs for a low price but tried searching for it to no avail. i will provide my own spark plugs but any recommendations as to where to change it as it is too expensive in autobacs.

Hi any one here change your own spark plugs?? how to judge to tighnest of the spark plugs??

Hi Any idea where can I get those black hoses (9-15mm internal diameter) and plugs that can withstand heat in engine bay? Tried those regular plastic ones from hardware shops but cannot stand the heat. Any shops that specialise in hoses and plugs? Tks

During the last servicing, I request for a full servicing since immediately i got my 2nd hand car. I requested for a Denso iridium but it turn out to have a NGK copper plug installed inside. Fine... little did i realise the spec for the plug is a bit off in the spark position parameters. Its +1mm more. I always wondered why my car got this weird pulsing engine vibrating where it thud harder than usual. After changing to the correct spec denso spark plug, I can feel a bit of HP increase and also the weird pulsing vibrating is gone. Morale of the story, always check what your workshop have done to your car.

Folks, Autobacs billed me $278 for 4 sets of original Nissan iridium plugs. Is it the normal price? Coz I find it to ex

Lesson 101 for Driver. The spark plug's location exposes it to extreme temperature variations, chemicals, fuels and oils. It is also attacked by cylinder pressures produced by the piston and cam timing, then it is also assaulted by high-output ignition units. As a result of all of this, one can effectively learn what the engine is doing by reading the firing end of the spark plugs. By careful examination of the plug's color, gap, and any deposits that reside on it, you will be shown the efficiencies as well as deficiencies of what is going on in the engine. Spark plugs should be checked at least yearly, and replaced as often as necessary. In most cases you can follow the manufacturers recommendations for replacement intervals. How a Spark Plug Works: The basics of a spark plug is that it must perform two primary functions. To Ignite the Air/Fuel mixture To REMOVE the heat out of the combustion chamber Spark plugs transmit electrical energy that turns fuel into working energy. A sufficient amount of voltage must be supplied by the ignition system to cause the spark to jump the across the spark plug gap, thus creating what is called Electrical Performance. Additionally, the temperature of the spark plug's firing end must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. This is called Thermal Performance and is determined by the heat range of the spark plug. It is important to understand that spark plugs CANNOT create heat, only remove it! The spark plug works as a heat exchanger, pulling unwanted thermal energy away from the combustion chamber and transferring the heat to the engine's cooling system. The heat range is defined as a plug's ability to dissipate heat. The rate of heat is determined by: The insulator nose length Gas volume around the insulator nose Materials and/or construction of the center electrode and porcelain insulator Now to the actual function: As the Ignition is triggered it sends the spark through the rotor, to the cap, down the wire and then it jumps the gap of the spark plug, a spark kernel is created that ignites the air/fuel mixture in the combustion chamber. Proper timing of this spark is not the only concern as described above. You must have the proper heat range as well as the correct gap. Opening The Plug Gap: On weaker or stock ignitions, opening up the gap CAN increase the spark kernel size, thereby creating a more efficient burn. The problem lies in that any added gap creates more strain on the other ignition parts. Coils may not have enough stored energy to fire, or in the least case, not enough energy to cross the gap, creating a miss-fire. Plug wires will break down due to the added resistance as the spark tries to reach ground. Rotor and Cap, as well as points (if you still have an interest in prehistoric ignitions), and the carbon bushing in the center of the distributor cap will show early failures. All of this is because the greater the gap and the higher the voltage requirement to jump the gap. Do not forget the gap between the rotor arm to the distributor cap too. A high performance rotor is a bit longer at the tip, allowing less spark loss or chance of spark scatter in the cap as the spark attempts to jump the plug gap. It is also possible to slow down a car if the gap is too big. Spark Plug Heat Range: A spark plug's heat range has no relationship on the actual voltage transferred through the spark plug. Rather, the heat range is a measure of the spark plug's ability to remove heat from the combustion chamber. The heat range measurement is determined by several factors: The length of the ceramic center insulator nose The insulator nose's ability to absorb and transfer combustion heat The material composition of the insulator The material composition of the center electrode The longer the insulator nose gives you a larger surface area exposed to combustion gasses and heat is dissipated slowly. This also means the firing end heats up more quickly. We are talking about exposed ceramic length, not extended tip length. The insulator nose length is the distance from the firing tip of the insulator to the point where the insulator meets the metal shell. Since the insulator tip is the hottest part of the spark plug, the tip temperature is a primary factor in pre-ignition and fouling.The spark plug tip temperature must remain between 450

Hi Guys, I'm looking for a replacement spark plugs for my Toyota Fielder. Original plug was Denso's FK16HR11. I've checked the stockists and found that they don't carry this but do have other Iridiums/Platinums for replacement. Some of them carry FK20HR11 which I found that was the standard part for 2006-2007 Axio/Fielders. But since 2007 onwards, Toyota fitted FK16HR11 in new deliveries. I've checked the Denso catalogue for spark plugs and I didn't find the normal copper plugs equivalent. Has anyone replaced the plugs on a axio/fielder with a copper one?

had been 3 good years and i reckon is high time to change my plugs......i want to get the attached pic.....any where to buy them...wanted to try motorcycles accessories king Lim Ah Boy. that fellow sell lotsa things if Satis Int'l is the retail for Denso...who then is the retail for NGK???? can drop me a tinker [email protected]

Hi bros, not sure if any one has encounter with oily spark plugs.. i pull out the injectors and plugs, they are all oily instead of dry.. must be a leak defintely somewhere.. pls advice on the needed replacement parts to get from stockist :)

My friend asked me why his Camry spark plugs has some oil. His car seems to be eating oil. I believe some seals are leaking. What do u thinking is the problem and cost of repair?

http://www.brisk-sparkplug.com/ I think the distributorship is in Malaysia which explains the RM currency. The regular plugs are only available in bulk orders. The Pt and racing ones can be ordered individually. However, I am not convinced about the premium plugs. How can the spark jump on all directions? Even in mult-ground electrodes, only one ground is preferred by the spark. Electricity does have a mind of its own. The mind of the shortest path.

Has anyone tried Iridium Laser? It is better?

Last week, my car misfired in the morning. By afternoon, the car is choking and sounded like a VW Bettle/Harley/Heavily modded WRX ! Misfiring heavily. Pop over the C&C satellite service center. They suggest plugs problem, but since they don't do diagnoistic, they suggest I pop over to their main service center instead. By weekend, the car is quite undrivable and I got the plugs changed over the weekend, and had a shock of my life when I look into plug 1 hole ! This is on my Airtrek, and apparently water goes thru the air scoop and seep through the spark plug cover and settled in the spark plug bay. I believe the water are all flooding around plug 1 and seep thru the rubber boot down the plug well. From the look of it, it seems like it had been rusting for 3 to 6 months, which actually coincide with the extremely thunderstorm that we encounter since December till now. However, C&C claimed that they've not encountered any other complains and suggest I leave the car with them to test by spraying some water on it (which I doubt will be equivalent to the thunderstorm that we get for hours). They do not have a solution for it right now :-( I doubt I'm not the only one facing this problem (apparently, EVO and Airtrek both have this problem, based on the forums that I read). Other countries I guess is not as bad, but in Singapore, with the car park under the rain for HOURS with, say a cold engine, I believe water will seep thru the spark plug cover eventually. Any thoughts on this ?

Hi Bros out there, My Integra is going KM for 80k servicing. Intend to change my standard plugs to NGK Iridium plugs but not sure which is the correct type. Can anyone here advise? Heard should be iri6 but not sure if the IX can be used. My ride is fully stock. TIA.

Does any1 knows the impact of using higher temperature plugs instead of those as indicated by car manual. For eg. Using: Denso irdium IK20 spark plugs Manual: Denso irdium IK16 spark plugs

Hi guys, I came across Autolite plugs in the USA. http://www.autolite.com/ They're suppose to be a Honeywell product. Anyone tried them before?

Wonder if it's worth changing to Bosch Platinum IR Fusion spark plugs? Has anyone noticed significant difference using these plugs?

Esp. when carrying more people with AC and low RPM. Side gap + regapping your spark plugs will help to improve performance by quite a noticeable amount. My original gap is 1.1mm and I increase it to 1.4mm. The difference is very noticeable. Tried with 4 people + AC and under hot day, the car performs well. I can't really feel the extra weight of the car at all. Even going up slope is not a problem (mine is manual). Of course, you have to experiment whats the max gap for your car. If you experience misfiring under WOT at high RPM, this means the gap is too big already. One cheap solution to get reduce misfiring problem is to install an ignition booster. Not those VS, its those which boost the voltage to ~16V. With slightly more primary voltage to your coils, you will achieve a higher secondary voltage to your plugs, hence resolving the misfiring issue (of course there is a limit as well).

Anyone have experiences with the NGK power cables and G power spark plugs? Power Cables claims the following: NGK's Power Cable is a performance spark plug cable designed with ultra-low resistance (0.9kW/m). The ultra-low resistance reduces spark energy loss, thereby improving acceleration, delivering smoother idling, and burning fuel cleaner. NGK's patented hyper silicon jacket minimizes voltage leakage, is resistant to heat and chemical corrosion, and it is reliable under extreme conditions. It's the hyper silicon jacket and the ultra-low resistance that allows NGK to maintain the factory diameter wires and provide the performance you crave. * Ultra Low Resistance Reduces Spark Energy Loss * Improves Acceleration * Delivers Smooth Idling * Improves Fuel Efficiency G power claims the following: Improved Fuel Efficiency, Lower Emissions, Quicker Starts. * Fine platinum tip reduces required voltage * Extremely durable under high heat *

Any bros know what are the signs to look for when you need to change the spark plugs? Read that its between 40k to 80k depending on the type of plugs that you use. Since the day I bought my car, i have driven nearly 40k without any problem from my engine. But one day just happen to talk about spark plugs with my friends hence the question of "when to change"? Any inputs or advice?

Hey guys thinking of swapping back to bosch plugs called them but they mentioned they only have double platinium for my model no ir fusion how's the performance for bosch?

My car uses IFR6E11 iridium spark plugs. Manual says check every 40k and replace every 160k ! Is this wise ? In my old car, I change every 10k (the std plugs)
