Thread: NGK Tr6 V-power plugs part #4177

Ive heard a lot about these plugs, pretty much all positive things. I was told that theyre 2 heat ranges colder and good for making power. Im currently running NGK Tr6ix which are great but now its time to change the plugs and im going a lil cheaper this time.

Anybody familiar with these plugs or has ran them? im assuming with these plugs that .050" is a good enough gap for making power. im not sure the life span of these plugs but i really dont want to gap too small (.035") just to compensate for life expectancy. I may go as low as .045" but you guys may know the perfect gap for theses plugs if youve used them

yeah, i tried the search bar... definately nothing specifically on NGK Tr6 V-power #4177 plugs. but yeah, im aware of the search bar. Anybody with info on these plugs please feel free to add your experience on them.....

i have no experience with these plugs, but ima assume that bc these plugs are Nickel alloy that .050" would be a good gap for good combustion while still allowing the plug to last a good amount of time. i know most other plugs we gap around .052"-.057" for max combustion, but these dont have a long life span so .048"-.050" may help with the life of the plug.
