not necessarily true about running specific plug for manufacturer but it is a safe rule of thumb fershur

they never worked in my jl or c6. OS did well but the local shop always runs out. I tried dynomite when they had nothing else and it did so well thar I went back and got the whole sheet. They seem to tune well and last a long time.

O.S and Novarossi plugs are the best IMHO. In my plus4, nova plugs works better so my vote is on NOVAROSSI.

I running P3 and P4's in my Ninja JX and they have been working great, no complaints. So it got my vote.

For basher vehicles like Savages I recommend Mccoy plugs.

Werks plugs for me since they are the plug-of-choice for my Clocked B5. When your engine modder recommends a plug you'd do well to listen...

My friend got his Clocked B5 1st, and it promptly destoyed a P5 OS. When i got mine i started with werks #6 with no problems to date.

Out of curiosity, how often you guys change your plug? How long does your plug last?
