I'm going to buy a Cobb AP (stage1 CNA gas) in a few days. I want to order plugs and coils. I've researched and found that I should buy the 997 Bosch coils but I cannot find what spark plug should be used.
Thanks for your help.

 

stock Bosch 7410...same as any stock+ car

 

Denso platnium spark plugs and gap them to .024 - .026

 

I went Bosch

 

OEM FR6LDC plugs. Take them out of the box and put them in. The wheel has already been invented, I'd worry about other stuff...

 

Plus one on the factory plugs. John is correct but the Beru are LDU for the update. Just tell them you want to order for a 2004 GT2. They have all been superceeded but just in case. The Denso platinum gap tight are really good but that's for cars running major boost and aggressive tuning. Factory plug works wonderfully up to 700 hp and 1.6 bar of boost. They really did the homework and run a dual prong staggered gap. Better yet, I realize I still have it memorized LOL 999.170.195.90

 

IMHO, avoid the Beru LDU's and go for the Bosch LDC's...ask any parts store for Bosch 7410 (internal call name for FR6LDC) for simple and correct choice.

 

Both work great. Just no Beru LDC
