Yep, .028. Make sure to only use copper plugs, none of those iridiums. NGK BPR6ES's are great for around a stock boost pressure.
yep .028 on all 2.0 n/t and turbo because of our coil packs if you gap any bigger the coil packs can git a lil spiratic because out coil packs are crap
A Big +1
NGK BPR6E or 7s if your modded good If you have anything else you deserve to be slapped.
Be sure to use a switchblade style gapper/feeler gauge and NOT a disc.
This is incorrect. These specs are from the FSM.
.028 - .030"
.048 - .053"
.039 - .043"
Will NGK BPR6EY spark plugs work on a GSX? Im having idle issues though i have E3's in there now so i bought some NGK.
Yes, they'll be fine.
If you are running anything greater than stock boost, or are running a larger turbo, I would suggest running 7series NGK plugs. Also, it will not hurt you to gap the plugs down a bit compared the the FSM if you are modded at all. .026 should work out pretty nice for ya.
If you have some sort of complete build, you should be able to read the plugs well enough to tell you what to do.
Do not use a flat blade. Use a wire. Use it at 90° to the side electrode.
