I just got the a Brothers Catalog and they have a 65mm twin TB for the '99 cobra. I dont plan on going forced induction but want to start getting more air into the car. I am also thinking about the C&L mass air meter. Does anybody have any recomendations on the 65mm vs the 62mm for a N/A cobra?

Don't buy it. The size of our factory throttle body is the same as most aftermarket LT-1 camaro throttle bodies are. The throttle body on our cars is not a restriction. Most likely, you won't see any gains with this piece.

Josh is correct, nothing wrong with the stock piece at all.

In fact, more people have lost power going to an aftermarket throttle body (as well as idle problems and other issues)....so I'd just stick with stock.

Improve the exhaust first.... some headers, offroad pipe and then look at the intake side.

Thanks guys. I have been weighing the intake vs exhaust and in other cars I have notice intake helps a great deal.
