maf and throttle body diameter

[Homeboy981]

Here's my version of the Cold Air Intake system.

This is Stage1 - using factory air tubing with MAF in factory location and HUGE air filter!


Large Conical Air Filter - it is 6"X11"...


MI Stage1 uses the mesh "screen" from Factory airbox...


You can see the Air Filter peeking through the Factory Side Intake...


This picture is hard to see but a lot has changed from the Stage1 configuration….

1). The MAF housing has been moved to 1" before the Throttle Body
2). Using a Honeycomb Filter to straighten airflow.
3). Using larger diameter silicone tubing - 4" to 3.25".
4). Although it looks rough on the outside, the inside diameter is SMOOTH.
5). Computer has adapted and I am getting SAME GAS mileage as i did BEFORE change, i.e., 22 city and 26 highway - under not-so-gentle acceleration. Average is 350 miles out of a tank.

LOVE the extra power, especially over 4200 RPM. It flies over to the redline now, instead of loping along to the redline.

Getting a Cat Back exhaust system today so we'll let you know how much she feels after "setting the engine FREE"! Love the car now with more power!

Would highly recommend. It DOES take time to get the intake right. If you need designing yours….PM me for details.

Thanks to everyone who helped!

The Downside: I need new tires now!
