Do you have a stock cam? If so, I would keep the Cobra intake. The stock cam and that Cobra will help give you a nice low torquey feel. If you have a higher revving cam, then I would go with the Holley to give you a much longer power curve.

Okay. The truth is, both intake manifolds are good. Which Cobra intake do you have? The one with an elbow connected(94-95 cobra) or the Fox body Cobra(93)? The Cobra is good for making low end power and torque. Past 5500rpm and it falls flat. A good porting job can really wake them up as well as there is plenty of room for porting. But you can only open up the ports so much. I have a GT-40 intake w/an unported lower(same as Cobra) on my supercharged 95 GT and it retains great street torque. But it is a restriction. And this is where a Holley would really shine. The ports are much larger and it is meant to rev. You can take them into the 6000rpm+ range. It's something that would really benefit my car. In your case, I would stay with the Cobra unless you plan on any forced induction down the road. You'll have great street power.

Personally, I'd keep. You can also get the lower ported by Tmoss for about $120. It will flow similar to the Holley for much less. But if you really want a Holley, then go for it. It's your car.
