Injen CAI Install

[MikeHTally]

According to Injen, I need to remove the bumper to install the CAI. I'm a fair wrench-puller, but that's a bit intimidating. I saw the "how-to" for an earlier model, taking out the inner fender liner. I've never done any body work (not intentionally anyway , so it all seems a bit too much. Also, while I'm askin', are there rear bumper covers for a 2008 1/2 MS3?

I have a suggestion for you!

Repackage that Injen CAI and send it back for a refund and buy the Cobb SRI instead and pocket the $100.00 bucks or whatever you saved. It takes about 20-30 to install and you don't have to go thru all the trouble of removing bumpers, etc.

Haven't bought anything yet. Educate me. I'm used to big, pushrod V-8s. I can do lotsa stuff to my "C" and the Ram, but it's been a while since I had a transverse (or otherwise) mounted four-banger. What's the difference? I assume "SRI" is Short Ram Intake?

Cobb Tuning SF Short Ram Intake System
Application: Mazdaspeed 3
Years: 2007 and up
Part Number: 771500

Netting a + 11 lb. ft. and + 16 HP (Mustang Dyno @ high elevation), the COBB Tuning SF Intake for the Mazdaspeed 3 utilizes a custom CFD design to maintain optimal flow and generate ideal performance. The OEM MazdaSpeed 3 airbox is the most restrictive stock intake we have seen to date. Simply replacing it with the COBB Intake will allow your MazdaSpeed3 safe and consistent power gains!

The custom conical cloth filter feeds filtered air directly to the engine, while maintaining optimal intake velocity and minimizing turbulence found with many aftermarket intake systems. This makes this a great aftermarket performance part to add to your MS3.

The Cobb SF Intake system for the Mazdaspeed 3 utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence that can cause engine management problems. From a custom conical cloth air-filter element, Cobb uses a CFD-designed velocity stack leading to an unique air flow straightener grid. This straightener grid is specifically designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. This eliminates the "dead spots" that can be experienced by poorly designed aftermarket intakes due to turbulence. NO other aftermarket MazdaSpeed 3 intake system utilizes all of these critical design elements.

In order to provide a system that looks as good on the outside as the technical advancements happening on the inside, Cobb utilizes a one piece design constructed from a high temperature plastic composite. The plastic composite material offers heat rejection properties that help keep intake air temperatures cooler. In contrast, intake systems constructed using metal castings or piping can actually retain underhood heat and in turn heat the incoming air.

I've got over13,000 trouble free miles on my Injen cai. Install did require the removal of the bumper, but it was no problem. Mileage improved by 2-3 mpg, the sound is awesome, the torque is even better. Buy what you want. The Injen is great. the MS cai is too. Neither will affect your warranty if installed properly. Take your time to decide on what you want to buy, take other posters recommendations with a grain of salt and have fun. My application netted me 24 hp and 31 tq. The real story is getting rid of the stock airbox any way you can. It chokes off any possibility of feeding enough air to the motor, even under low throttle application situations. Just get out and enjoy the car!

you DO NOT have to remove the bumper. trust me, i removed it and it was a pain in the ass. i didn't even get it all the way off because i couldn't figure out what i wanted to do about the fog light wires...

anyhow, i put it back on and just took my two front wheels out and got to the front splash gaurd bolts through the holes in the front grill. save yourself a lot of time and anger. pulling the fender liner is very easy, just a couple screws.

Just unplug the foglight wires. It took time, yeah,but it wasn't hard. The toughest part was finding a place to lay the bumper cover once it was off the car.
