What do you guys have your spark plugs gapped to?

[DarkCreep]

Sup all..

Right now I have NGK V-power plugs gapped to OEM specs. The shop that did the tuning told me I need colder spark plugs and told me to get the BKR7E but the CC DIY told me to get ZFR6F-11 so I ended up getting these.

The shop also told me to gap them at .25, is that correct?? OE is .44 or something I want to double check before they come in the mail.

PS: After the tune I was getting amazing MPGs, perfect idle, and car was fun to drive, but all that reversed. Is it because of the spark plug? and the car sometimes smokes black and is running too rich.

11s seem a lil hot, i used colder plugs on all my turbo sets ups. like 8s sometimes even 7s, its usually 2 steps colder, depending on turbo application and boost pressure.

7 range is the common plug to use. If the BKR7e11 is unavailable, then there is an optional NGK 7 plug to use. Gapping them at .25 is a good place to start.

x2....thats the plugs i have and i have my gap set to that. if your running a big gap you might run into the spark being blown out under boost
