yo Lotus,
I could not get any sound.
What are the results?
Project M.P.G FOUR WHEELER Magazine
miesk5 Note, Results are Comparable to Tests in other Ford Engines
here is an "Air Cleaner" Comparison Test in Project MPG using a 460 gas powered 1988 Ford F-350 4-Door, Crew-Cab 4x4 dually, converted over with a Bronco back half by Centurion in Michigan
Detailed results can be found in the numerous charts, tables and graphs found in the 1999 July through October issues of Four Wheeler Magazine

Here are the Intake Temperature Comparison Tests, Stock vs. K&N®in factory air box w/insulated air tubes

"Cheap Tricks
Since you already know that cool air is happy air, then what about all that under hood engine heat? The cooler you can make that engine compartment, the cooler the air intake system will be, and the more aircharge can be had. Wrapping the exhaust manifolds with insulation or having them ceramic coated will help, as will venting the hood with a scoop will also help.
Another neat and cheap trick is to insulate the air intake tubes with a heat reflectant tape in order to keep the incoming air as cool as possible. Even though the metallic intake manifold will undoubtedly transfer heat throughout the intake system, the rushing air of the incoming intake charge will inherently cool the insulated components from within.
DEI makes a product called "cool Tape", which is an adhesive backed 1.5 inch wide tape with a metallic silvery heat resistant exterior. This tape is available in 15 foot lengths and sticks to almost anything. Dyno reports have confirmed that at least one percent of the overall horsepower is gained for every 10 degree decrease in temperature, and even more if the coolant temperature is stabilized under load. We could feel the difference, even though ever so slight. However, we could really see the difference in the fuel mileage increase. Not too bad for just a couple of rolls of tape. .."
Ken did similar insulation;
Air Tube & Box Insulation pics in a 94 5.0; Ken used Reflectix Insulation, avail @ Lowes. etc. ST16025 - 16" x 25 feet. miesk5 Note; Ken installed the K&N® & removed da cold air intake tube that runs to the top of the radiator; but he could have installed the intake tube section later.
