18 psi spark plug and gap

[dustin_8907]

Going ahead and getting new spark plugs, what ones and gap for 18 psi?

Also after my new tune I will be running 23 psi. Will I have to change sparkplugs after the tune or can you give me a good gap to run both so I don't have to change them for the new tune in a month or so.. Thanks

bpr7es? Can you be more specific with gap?

bpr7es are good, they are what i run on 21psi. mine are gaped to .27

i agree on bpr7es, gapped .25-.27

Used to you could call a parts store and actually ask for a "bpr7es", some stores you still can but a couple stores in my area now use the ngk part number which is a 4 digit number, the ngk number for the bpr7es is 5534.

Everyone (except the OP) in this thread is lucky I don't just go hand out negative rep for your incorrect information. Spark plug gaps are in the hundredths position, not the tenths position.

These should read .020-.028" in this thread.

my bad, worked all night and just got up. I guess reading it from the prior post incorrectly caused me to write it the same way. I'm sure he would have a hard time gapping them over a 1/4". It's not like i did it on purpose, and he would have a hard time finding a gap wrench that went that high!
