Im going to be spraying next spring, and I'll be doing my header install in 1 week. Im going to put TR6 plugs in there for the spray coming next year. Will these plugs affect my daily driving? How much power would one lose NA using the nitro plugs?

 

1>2 hp if so.

 

i know i installed my headers with TR6`s so i can spray soon too and i dont know if its the jet hots or the plugs but i felt the loss in power after the install then the dyno backed it up i actually lost horsepower :O( if the tune doesnt fix it im gonna get done mines getting sold

 

When I changed from TR-55's to TR-6's I didn't notice any difference in power even with the much smaller gap on the TR-6's.

 

I didn't notice any difference.
