plug for tuned car

cmotzner · 08-07-2014, 03:33 PM

What spark plug do you recommend for tuned back end flash with e85?

Thanks

DuDai · 08-07-2014, 03:33 PM

Just the regular ones that would be coming with the car. Just going to have to replace more often.

I run the ngk's.

The regular bosch ones will do fine

Use the OEM Bosch plugs. They handle all the additional power well with the only affect being shorter lives - they'll require replacement every 20-25k miles.
Any plug for a tuned 335i will require those short change intervals anyways.

Higher boost can make your car more susceptible to knock so for my car I choose to run the 1 step colder NGK's... High mixtures of e85 can cause "hiccups" first thing in the morning though !

If you want to push the car for more performance, you need to get NGK 5992 and gap it to .022. I used both. The OEM plugs does last long. The OEM plugs only lasted for 10k miles before they start to missfire.

For an FBO+E85 Tune Car or anything higher power, you should be using a properly gapped NGK 5992. Otherwise the OEM/Bosch plugs are fine.

I think it was .22 that did the trick for me!

What about just a regular jb4 (map 5) that mixes a few gallons of e85 every so often? Bosch will be okay for me or should I switch to NGK?

From what I have read the ngks don't last long either.

Bosch or NGK are fine.

It's really a matter of budget and laziness.

Bosch are a little more money. NGK are a little cheaper but you need to gap the NGK where as the Bosch come pre-gapped.

Supposedly the Bosch last a little longer then NGK.
