The only other thing of note, however, is that many on AW have clained these come at "stock" gap in both applications. Get a gap tool, as 1 of 4 plugs were gapped at .032, the rest were .035-.040. Not a big deal to fix, obviously, but it seems like it's always a good idea to check.
Is your definition of high boost just anyone w/ a chip (0.8 to 1.1 bar)?
PS I had mine gaped at 0.028 is that right? (0.032 - 0.004 - ATW, 1.1bar)
the bentley manual suggests .028 for the 1.8t's... that is the only time i heard that being used for a gap. just my .02
Believe it or not apparently the AEB engine has a different gap spec .... go figure :roll: SpecificationSpark plugs (AEB, 1.8L engine) Gap 0.70 to 0.90 mm (0.029 to 0.035 in)
Chatting with some race techs at the track and reading through Vortex (not the best source I know) and ClubB5. The general rule seem to be for every +50 hp = one step colder - 0.004 spark plug gap. I figure my chip gives me just about that, so the BKR7E @ 0.028 seem to be about right. I don't know a 100% if that is right because I have not tried it before. But I'll give it a try and will report further.Here's one thread that I found on the subject: Plug Gap
Glad to hear you're happy with the new plugs.You said, "I would suggest these coppers for anyone in a 1.8t." I would not. For a stock 1.8T I would recommend stock plugs. Additionally, depending on the state of tune, you could go two heat ranges colder, sometimes even three for crazy cars. I've been using the Bosch F5DP0Rs successfully for a while now. It is what several tuners recommend for higher HP 1.8Ts.I'm glad to hear you're happy with what you've got. That's all that matters. However, I would hesitate recommending one plug for every 1.8T out there, regardless of tune.
Rusty~The F5DPOR is a single electrode plug. I think they're one heat range colder than stock. The best price i've see on them is about $12 each. This is one single-electrode plug that you've seen in action working on the AEB. I think you'll agree it does the job just fine. BTW, I'm getting the new springs on in about three weeks. That with the r-comps should shave another 1.5 to 2 seconds per lap.
Yeah, and the "normal" price is around $20 per plug. I know it's not cheap, but how much has everyone put into their cars to this point? To have the right plug in there for an extra $30 is a drop in the bucket, especially for the long life....
Has anyone tried those new Bosch Platnium +2 or +4 plugs that don't have the hook electrode, but two or four side electrodes? They look like plugs you pull out of F1 or Indy car engine. Mazda Rotory engines have always used plugs that look like that with the side electrodes. Its very Intresting to me. Its Bosch so it can't be bad can it?
