Its due to the door design too.. The front door is longer and the weight of it u can see its nearer to the B pillar.. The rear door is more heavier looking towards the B pillar compared to the C pillar end.. where it has the curve for the rear wheels.
Well nothing is better that real world knowledge. When i went for Denso last time i did my research ady..
I took out my spark plugs and did a regap it at around 40k km. Thats like around 32k km of mileage since i changed my plugs at 8k km mileage.. clean plugs with no sign of soot or lean redness.
Regap the plugs back to stock specs, which is 1.1mm. but u can go closer to like 1mm or 0.9mm.
After regap the plugs will function like perfect brand new plugs.
Y they say performance plug spoilts faster? its due to the electrode being more finer than Tough series which is 0.8mm. Every spark the plugs put out, a miniscule amount of the electrode will be gone together. Thats call wear and tear. So technically, a 0.8mm electrode should tahan 2x times the mileage of 0.4mm if the amount of sparks generated throughout the mileage is EXACTLY the same. However due to different driving conditions such as high rev all the time will cause more wear and tear.
Therefore a performance plug which is tend to be driven at high rev most of the time will show lesser lifespan than standard plugs which were calculated on normal mileage at lower rev and also thicker electrode.
Y spark plugs have problem such as misfiring after a while? its because of gapping voltage. gapping voltage is the voltage required to bridge the electrodes. the thinner the electrode, the lower the gapping voltage. the nearer the electrode to the ground , the lower the gapping voltage. Thats y denso misfires very less. its thinner electrode gives the advantage. Over time the electrode will wear off and the gap will become bigger. So a regap will bring it back to brand new performance level.
So conclusion is. Ur IT20 Iridium Power also can last as long as regular plugs, if u do a proper regap. However if u regap it with an inexperienced person or a person who does not know how to do it, there are too possiblities.
1st the electrode pin bends. Causing irrepairable permanent terminal diec0ck damage to the plug. Continue to use it will cause instant damage to ur engine.
2nd, the gap becomes too near. When the ECU is unable to specify a gapping voltage that is low enough to time it properly due to the much lower gapping distance, ur sparks will jump a bit too soon. causing detonation. then ur engine will become like ckdenion punya.
U mau beli R3 rim only? R3 Rim only for sale also. Offer me. Ori price is RM1920. Lowballers will be sarcastically replied.
Cusco so far the best.. But too bad dont have stock.
Sorry bro.. Need to update u all.. The current batch stock also finish.. 1 Gen2 club came and sapu every single bottle.. so have to wait for the next batch in nov. But since there is so much demand. In the future when there is stock i will straight take as much as possible and then put it for sale here since there is a lot of demand for the oil.
diecock, need to wait so long mean I need to go service my car first. cannot wait edi. haha. nice info on the spark plug. din know about it. but how do i even know if the person that gap the SP do it correctly or not??
