someone told me about cold air throthle body is that an ok method of adding horsepower to my car
You are talking about two different things. Putting a cold air duct to
your throttle body is one thing,a bigger throttle body is somthing
else.
1 - Cold Air: This will give you some small gain in horse power, maby
5 to 7 Hp. It will make for a smother throttle response due to the
computer having the same air temp. at all times.
2 - Big Bore Throttle Body: Lots of problems here. If you do not
increase the size of the injectors and reprogram the computer you will
waste your money on a small Hp. gain.
3 - THE BOTTLE! (NOX): This is the best bang for the buck. A good 100
Hp. kit will not set you back much money. It is, if you are like me a
Gear Head, easy to install. The hard part is tuning it for your car.
Find a local sports car nut running a Honda or Toyota he can point you
the right direction for help.
Good Luck
