Dear K&N,
I recently purchased your 14" X-Stream Air Flow Filter Top and a Stubstack (Holley Square Bore with Milled Choke Horn) for my 73' Plymouth Cuda (340 4bbl, 4sp) that my father and I restored and the results are amazing. The motor is far from stock but still primarily designed for the street, however I was never able to get the 650 Holley (double pumper / mechanical secondaries) adjusted right, the car just wouldn't choke the fuel which I always thought was kind of strange. This was partly caused by the lack of hood clearance, forcing the use of a 1-1/4 drop base and a filter height of 2-13/16". Even with the air filter assembly off, the car still seemed to bog a bit under full throttle and ran worse towards the top end, most likely due to the air flow going over the top of the carburetor instead of down into it. With the help of the information on your website I decided to take a chance and see what the parts above would do. As soon as my order arrived I installed the parts, which took all of 2 minutes, warmed up the car and headed out for a test run not sure what to expect but never expecting what I got. In 1st gear from about a 5mph start, usually I would have had to be running 25mph or 3,000 RPM, I let it loose and found that I was driving a whole new car as it caught rubber from 1st to 2nd before I had to get out of it. I always knew the motor was strong, that's what I had it built for, but until I installed the X-Stream and the Stubstack the car was never reaching its full potential. The Cuda runs stronger than ever now and the drivability is on a completely different scale. All I can say is Bravo, I'm beyond impressed.

Thanks for a Sweet Product,
