bought a set of the ngktr6's today wondering on any special gapping preferences, or horror stories.

 

I think that .040" is the proper gap for the 3 lb pulley you have. That's what I'm using with my 5 lber.

It can take from 2 hrs to 6 hrs for a non-pro, shade-tree mech. I took 4.5 hrs to do my first change . Be sure you have a 1/4" drive 7mm universal(swivel) socket to get to the #6 coil pack bolt.

I run TR-5s,but I think most people run the TR-6s.Tr-5s are only a half degree colder than stock plugs but they are copper instead of platinum.I gapped them at .044.

Thanks again to LTNBOLT for this page.There is good info and tips here.

I wounldn't recommend the TR6 with a 3# pulley either. I like the TR5 also gapped @ .044. I ran the TR6 for about a week and a half and fouled them out to the point of missfireing with my daily driving. If you stay in the throttle a lot and do a lot of racing they may be ok. Now if your going to a 5 or 6# pulley yea the TR6 is the plug to use with about a .040 gap. Tha gap will be closer with the added boost.

 

I ran the TR6's all last year with a 2# lower and a 1#upper pulley and had no problems

 

whats the part number on the TR5. I have TR6's in now with only a chip ,90mm and filter and have started getting detonation. I think it might be the plugs Opinions?? Oh its a JDM chip I haven't checked which Program or called Jim yet I just figured plugs?
