Hello Everyone:

I just cut the muffler off of my 2004.5 CTD and replated it with a 4 inch pipe connecting to my existing factory 4 inch. I added an awesome 5 inch tip 18 inches long and it sounds great. My fuel mileage has increased and I am interested purchasing an air intake system.

What do you recommend? Does anyone have a AirRaid with the MIT installed? I travel about 1,000 miles a week and would like to increase my fuel mileage. Any feedback is much appreciated.

 

I use the AFE Stage II system but put it on the second day I had the truck so I cannot speak to mileage gains. Love it and I had the AFE on the Power Smoke and Duramax before the CTD.

 

Thanks for the advice. I am still intersted in learing more about the AFE vs. the AirRaid?

 

AFE has 7 layers if you get the proguard filter. It has superior filtering with good airflow!!

PS go to their website. advancedflowengineering.com I think.

 

I had the Airaid with MIT for about 3 months, and I am currently running the AFE Proguard 7 with torque tube. The mileage is no different between the two.

Turbo noise is more pronounced with the AFE torque tube and boost is slightly higher. I switched systems to get a complete torque tube from filter to turbo instead of insert.

FYI the Airaid is also a 7 layer filtration system and, imo, did a great job with airflow and filtration.

The exhaust made the biggest difference for me on mileage. The intake had a minimal effect on mileage but improved other factors...airflow, boost, lower egt's.

 

price the AFE is about $125 CDN taxes included and the Air raid is about $95 taxes. I ordered the AFE and am awaiting for it now. Both seem to have a great rapore so pick one and be happy with it.

 

Thanks for the advice! So far I am experiencing about a 1.5 mpg gain goin to a 4 inch straight pipe. I had heard rumors about backpressure etc...ALL I CAN SAY IS MY POWER HAS NOT BEEN HURT AND I am LOVING the new sound!

Who has the best price for AFE or AirRaid?

 

Diesel Manor has the best price on the stage one with proguard.

I just got mine in the mail yesterday!!!
