Modified air intake box, Hack & Saw

I decided to open up my stock air intake box to improve the air flow, I just work to hard for my cash so I can`t bring myself to throw away 400+ on a high flow cold air intake when it`s not even a cold air intake due to it drawing in more hot air from the engine bay than my stock hack & saw jobber.

I can`nt up load the pic`s but all I did was cut out the front from the bottom up to just under the part that clamps & seals the filter & back around the corners 4 inch on the fender side and 5 inches back on the engine side. Used my grinder & hack saw took about 15 mintues to do a nice clean job including the file job to smooth the edges.

I noticed a slight improvement in throttle and my engine seems to be running smoother. I`m still using the stock frame air filter and have`nt made up my mind to go with the K&N stock replacement or upgrade to what these 2 like minded gentelmen have done.

A cowl intake is another good, inexpensive choice for getting cool air to the engine while providing a higher intake for deep water crossings.

The intake manifold's temps are much lower when cruising at freeway speeds. This has been confirmed with thermometers mounted in the door jam and air filter box along with a ScanGauge, used to monitor the intake manifold air temperature.
It's built so it can be converted back to the stock intake in just a couple of minutes so I could experiment with it.
No problems after two years of daily driving. It is a little nosier when accelerating hard but quiet while cruising.
