Its super lightweight, keeping the cars center of gravity low, and is deisgned in such a way as to improve the air flow and cooling around the engine head, while the colour coating is very efficient at dispersing heat. Available in matt red, matt blue (above) and gun metal grey.

I RUN MY V ONE RRR AT 10.000 FT ABOVE SEA LEVEL, !!!!!!!!!
I HAVE A .12 TZ EB MODS WITH GREAT RESULTS SO FAR, JUST AFTER BREAK IN I TOOK THE 0.2 SHIM OUT AND PUT A P7 GLOW PLUG. I GET ALMOST 7 TO 8 MIN OF RUN TIME WHICH MAKES ME WONDER IF I COULD TAKE THE 0.1 SHIM OUT. SHOULD I DO THIS, IT IS SAFE FOR THE ENGINE HEAD TO BE INSTALLED WITHOUT SHIMS???

BTW guys.... i found out my TZ3 + max 2602 pipe combo to be very impressive all round.
