Price: $250.00 Pros: Better throttle response, more power, cheap and easy Cons: none so far Recommended? Yes
Comments: I have had the BBK 62mm throttle body on my zj for a few months now and from day one I've noticed better throttle response and increased power, which helped to compensate for my 32s with the 3.55 ratio i had. I would recommend this product to anyone looking for that extra kick.
Price: $180.00 Pros: It sucks... and it sucks wonderfully. Easy and efficient mod. Cons: None come to mind Recommended? Yes
Comments: As soon as I started my zj after throwing this puppy on you could feel and hear the difference. Opening the butterfly valve makes a sweet hiss and the added torque twists the frame a lot more noticably. Never dynoed it but it's a noticable performance increase.
