Spark plug change for the GTI

[dbias]

With the many upgrades to the GTI, the 93 octane tune and down pipe specifically it’s time to get the tune company recommended sparks plugs in there so it doesn’t cause problems.
Never heard of a non projected tip spark plug but here we are. Time to break out the torque wrench and get at it.

Where did you get your plugs? Dealership or elsewhere........? How many miles on the ______________?

That's a race plug. Odd that they spec'd those.

What kind of power are you making on the 93 tune to need those plugs? Even an R or base Macan with the E888 pushing 300+ HP uses a regular plug (Bosch 8516 or Bosch 8501).

Don’t need that but won’t hurt. That gap is gonna need maintenance.

Bought the plugs from BMP tuning. 2024 GTI with 16k miles.

My VW loved a steady diet of fresh plugs

Gaps checked out at 024 exactly as they recommended.

They say 331 WHP but I haven’t upgraded the inter cooler yet. The regular plugs looked fine but just had about 500 pretty easy miles on them with the tune.

Sounds nice and like you are having/planning some good fun with it.

Yeah I’ll have to see how things go with longevity. The stock plugs looked pretty good at 16k miles and it being direct injection.
Seeing how HP has been increased a little over 90 hp they recommend a one step colder plug which seems to check out from everything I’ve read. While I don’t think non projected was really necessary the remote possibility of preventing a ground strap blowing off and grenading the engine won’t hurt either.

It has been fun. Honestly the biggest change has been lighter wheels and near slicks summer tires. Being a FWD car I can’t believe how it takes curves now. The stiffer rear sway bar from the factory on the Mk8 appears to make a good bit of difference.

Wow - that’s a new one to me - well, since the 70’s anyway

Yup, very different. Thanks for the post.
