NGK BKR7e

Mr Belevedere and one cold etc are both right
BKR7E NGK REGULAR V POWER? Stock number #6097 says to use 4644
Cheaper $

NGK BKR6ES *STOCK heat range* <-- STOCK Plug

NGK BKR6E "V-Power" *STOCK heat range*

NGK BKR6EGP Platinum Plug *STOCK heat range* BKR6EGP NGK G power Platinum alloy stock heat range stock # 7092

NGK PFR6T-10G "Laser" Platinum *STOCK heat range* race plug

NGK BKR6EIX Iridium *STOCK heat range*


Autolite 3922 Copper Plug *One Range Colder*

NGK BK7RE Copper Plug *One Range Colder*

NGK BKR7E Iridium Plug *One Range Colder*



BKR7EIX NGK IRIDIUM one heat range colder stock # 6664 14 BUX Each in Canada

 

bkr7e ftw. autolites suck. end of story

 

i would either run ngk 4644 or autolite 3922. copper plugs are the best to run on cars with forced induction. i always stay away from platinum plugs. they're overpriced garbage.

 

cool thanks guys. the gap is .40 right

 

what would one stage colder do to a stock car?
