Title: Which spark plugs?
Post by: Dre on March 12, 2021, 06:15:25 pm

Service is due on my mk5 gti. Standard car with no mods. What plugs do i need?

Bosch FR7KPP332 or FR7KPP332s

I've had a search on the internet and people are saying Bosch FR7KPP332 but when I'm looking on gsf, euro car parts or even ebay it say the correct plugs are FR7KPP332s which show fit mk6.

Would appreciate the help.

Yep they are the ones R-tech put in my un modded car when they serviced it a few weeks ago.

Bosch plugs don't run quite right in these engines. As above, stick to the iridiums, or if you want an OEM double platinum at a fraction of the price, you'll be wanting NGK PFR7S8EG.

The OEM heat grade is 7. A lot of people think the BKR7EIX is an upgrade, but it isn't.  It's actually a far inferior plug to the OEM in terms of lifespan and build/materials quality, but they do run nicely  :happy2:

It could be placebo but the red coils + iridiums seems to run very nice indeed.
