NGK - TR55

I'm running NGK TR6's on my TVS blown LS3 and MP122 blown truck. I think my son's turbo charged GMC is also using them. They work well and they're cheap. In the world of high performance, you can't say that too often.

All of the supercharged and turbocharged Camaros and Vettes I am aware of in the DFW area use the NGK TR6's. They were recommended to me by LPE. :chevy: :chevy:

thanks a ton guys! i wish i could get another blower, but 7g's is alot of cash. im honestly really happy with how fast the car is stock. im planning on a zex kit in the near future for the occasional run to the track.
