i just replaced the plugs on my car for the first time (since owning it) the other day and i noticed the bkre6es-11's were in there, gapped to .39. i put in some bkre7's and gapped them at .30.

is it gonna affect the tune significantly at all? should i stick with the bkre6's? the car ran cool before, but i had a little issue with a roaming idle. now the idle is a lot better (thaat could be just cuz fresh plugs are in there) and it seems like the motor performs better under boost. i think my gas mileage mighta even went up (i just drove from atl to miami last nite)...

i searched but couldnt find a clear answer. my guess is if anything i might run a lil bit rich. i haven't pulled the plugs to check yet though. any info...lemme know. thx!

bump for an answer. i figure it's a noob question but someone must know something

why did you change plug type and gap from what the car was tuned on?

that's the thing. i bought the car boosted and that's the one thing i didn't check. bkr7e's are pretty much standard on boosted hondas so it didn't even cross my mind when i got the car...

it compression tested perfectly when i got it, it doesn't burn oil...no real issues with the car in the 12,000 miles i put on it since then besides the occasional roaming idle. i figured it was time to put some new plugs in so i bought the bkre7's and gapped them to .30.

i was surprised to to see bkre6's in there when i pulled the plugs. they had normal wear on them too. since colder plugs are recommended and i bought them already i figured may as well try them. that's why i'm asking if it will throw off the tune...cuz if so i'll either get a quick retune or just go back to the bkre6's. but the car runs better to me on the 7s tho...

after a couple hours of reading through old posts...seems like lots of folks have changed heat ranges and gap widths on their plugs without retuning. i just went one step colder so it shouldn't be too significant...and so far so good. guess i'm being paranoid...

no need to retune, i have changed different heat ranges before, nothing goes wrong

just no reason to gap the new plugs down. if the old plugs were perfect at .039 , then i'd gap the new ones at that. You should run as much gap as you can without inducing misfire.

i just went with the recommended gap width since the plug is colder. i think .39-.44 is the recommended width for stock plugs so i wasn't sure it would apply the same. i'll play around with it though. thx everyone for the input.
