Yes... Kenne Bell does. Also... it may be true that the flowzilla is worth only 50 HP on a stock Cobra but that's an engine limitation, not a blower limitation. Give Kenne Bell a call and tell them what part you're looking for. They don't list individual parts on their website. BTW... the 2.2L Kenne Bell "kit" I believe also includes an after cooler. You'll need to decide just how far you want to go with what you're attempting to do.
What year car are you trying to install this on? What blower do you have or are getting that you need only the lower intake for?
