Default NEW!!! 2 Piece 427 Carburetor Cold Air Box

Fellow Car Nuts:

We got really frustrated with the original style cold air boxes. They made putting on your carburetor tuning it a real pain. (Not for me as Thomas does all that work )

So, more accurately, Thomas got pissed off and made this new part to relieve himself (and all of you) the headaches.

You can use this cold air box to give your motor that "original competition look." It will need to be slightly trimmed to fit--depending upon which carburetor and intake manifold you are using. It was designed to fit on an FE Ford (390, 428, and 427). Due to the shorter distance between the carb and the distributor it will not work on a small block Ford 289, 302 or 351).

The purpose of a cold air box is to lower the temperature of the incoming air into your carburetor by shielding it from the engine heat. The colder air makes for a denser fuel air charge and makes for MORE HORSEPOWER. You can lower the intake charge temperature even further by using rubber weather stripping on the edge of the box to seal it to the underside of your hood. This is the latest creation from Kirkham Motorsports. We (Thomas) were tired of having to remove the carburetor every time we wanted to work on it because the original style cold air box was in the way. Also, it is difficult to install a carburetor with the original cold air box on your motor. So, we took a hint from the Ford GT40 MKIIB and made the top removable. Now, with our new 2 piece unit, you can easily install the bottom of your cold air box first, then install your carburetor, hook up your throttle linkage, and finally TUNE your carb without the cold air box being in the way. Simply mount and install the sides of the cold air box with 8 screws and you are done. When you need to readjust the carb simply remove the 8 screws and make your adjustments. No more headaches!

This cold air box is also a LOT cheaper than the 1 piece cold air boxes we make by hand in Poland. The original style cold air box is $425 (it is extremely difficult and time consuming to make). Our new 2 piece box retails for $250.

And a NEW YEAR'S SPECIAL!!! This normally retails for $250. For the next two weeks, we will sell them to Club Cobra members for $200 (+shipping).
