Hi all, I have recently received and installed my air filter that I purchased of Casey earlier this year. Whilst the design could probably do with some slight refinement, as I found the brackets that hold the lower filter housing in place required some adjustment, I am very impressed with the design. And I do believe that the car has had a noticeable increase in power without even changing the filter element. Just so that I did not think it was in my imagination I let my friend drive it around when we were in the local village and without telling him that I had installed the new airbox he actually said to me that it seemed "a little nippier than usual". I am not going to say that the difference was enormous, in all honesty I brought it mainly because it looks so much smarter than the original. Thanks Casey Nice logo on the side, it finishes it off nicely. Regards James RG Colchester England P.S. Does anyone have a reference for the K&N Filter element which fits the DeLorean? Preferably one that I can get in a UK shop.
