Do I Need To Re Gap My Sprk Plugs?

[zafeniak]

Hi guys,

Currently I have a r33 GTS-T, following mods include:

GReddy Front mount intercooler

Straight through 3 inch exhaust

Cold air intake with pod filter

turbosmart boost controller

My car runs fine at 10 pounds, no misfiring of shuddering at all.

I was reading a couple of posts and I noticed that alot of people gap there plug to 0.8mm, mine are currently at 1.0mm.

If I am not having any issues with my car misfiring, should I regap my plugs still or is there no point?

CHeers.

If you dont have an issue, you dont need to change the gap

whats the point in gaping?

Gapping the plugs smaller; making the distance between the center electrode and ground electrode smaller, makes it easier for the cars charging system to actually fire the gap, and make a spark.

Technically you want the largest / hottest spark available, to have the best chance of fully, and timely igniting the charge mixture.

With the above in mind (spark size determined by charging system ability) you only gap a plug smaller if your having issues firing that current gap size (due to poor charging system [old coils] or high cylinder pressure / turbulence)
