Spark plugs

Post by Grantkat »

After my recent lawnmover syndrome experience and having to have pulled the plugs to fix it, I am wanting to replace them in the near future. While they were clean, 2 of them are are starting to show wear.

the original part number is 30637308, which I cant find. what I am seeing from FCP EURO and other reputable sites is 8642660. can anyone say thats a direct volvo replacement?

What engine do you have? NA, low pressure or high pressure turbo?

Assuming the car listed in your profile is the correct car, a 1999 S70 GLT is an LPT turbo engine. These should be the plugs:

I don't recognize the first part number you list, but the 2nd one as far as I can see is very confusing as this Volvo website lists it as suitable for turbo cars, but at the same time saying it is for cars w/o (with out) turbos??

https://www.volvocarstorontoparts.ca/p/ ... 42660.html

The first one should be the correct one.

Single electrode plugs for turbo models

Triple electrodes for NA models.

I find copper plugs will need regapping at 15k or so , and new at 30k. If you buy from FCP you only buy once
