You can check the forums and it'll say the same thing your asking . It comes down to personal reference ,everyone (including myself ) that I run with in our 3rd gens we run NGK . Just make sure they are dual pronged and gapped correctly and you'll be just fine .

Pros: NGK dual pronged

Vehicle: Toyota 4runner

I went with NGK iridium's. The "book" says they should be replaced at 100k. I mostly didn't want to have to fight with them at 100k miles to get them out.

Pros: easy to swap, cheap

Mileage: 25000 km

Cons: negative ignition corrections

Installed the NGK rs7 plugs and it runs fine. I kept them at factory gap, which was, if I remember correctly approximately .028.

Pros: runs fine

I'm running PFR7Bs. I get a misfire or 3 here and there, only during low load low speed acceleration. I've got R8 coils too. Not sure if the RFD makes them occur any more frequently than they otherwise would, but I'm not worried about it.

Cons: occasional low speed misfire

Vehicle: Volkswagen Golf

Part number: PFR7B
