hi all just wanted to know which plugs to go with really. i have 97 uk turbo 2000 wagon only mod done is exhaust any advice will be great thanks guys. phil

 

Standard plugs is the answer really. NGK PFR6b, if you intend on modding it a lot more and getting another ECU etc then perhaps PFR7b, but I'd be using standards for now.

Hope this helps,

Graham

 

thanks mate do i have to gap them at all

 

yes....dont take it for granted that they are gapped correctly,always check.

 

where can i get the tool to do it what do i need to gap them to.

 

any body know what the correct gap is for standard plugs

 

Subaru's stated gap is, IIRC, 0.8mm. But you don't want the boost blowing spark out, so I'd try 0.7mm.

FTR, most modded cars (using the PFR7B plug), are gapped to 0.6-0.65mm - so at 0.7mm you should be okay....


You need a feeler gauge's correct sized blade to gap the electrode gap. Move the outer electrode in or out by very carefully using the force of a short screwdriver. The gap is correct when the blade moves around in the gap, but so there's a slight frictional drag too. If the blade is hard to move, then the electrode needs to be opened out a smidgen.

Some feelers might be in "thou" (thousandths of an inch) only, in which case:-

0.80mm = 0.031" = 31thou
0.70mm = 0.028" = 28thou
0.65mm = 0.026" = 26thou
0.60mm = 0.024" = 24thou

 

thanks for the info really really usefull. next question lol how do i get to them cos they are in a tight space do you go underneath?

 

It's a pain.

If you search "spark plug removal" | "spark removal" | "plug removal", then I'm sure you'll get the info you need...
