5 out of 5 stars Awesome product! - 06/11/2008
Review for: Black Mass Airflow Sensor
From North Carolina Reviewer: From A Customer   Own this product - Yes
Although I had to wait over a month for this part to arrive, It was well worth the wait. I installed this on a 99 chevy camaro that already had a volant cold air intake, magnaflow cats, and a borla exhaust system on it and it really opened it up. noticable power gains through the entire power band. VERY IMPRESSED

Review for: Blue Mass Airflow Sensor
From Texas Reviewer: From A Customer   Own this product - Yes
Great Product good price, its a good upgrade and adds more torque. You gotta have the cold air intake to go with the mass air flow sensor or it wont work the way its supposed to.

Review for: High-Flow Mass Air Sensor
From Antioch, CA Reviewer: From A Customer   Own this product - Yes
Vehicle: 2001 CHEVY/GMC TRUCK Silverado/Sierra 1500 Lightduty
Installed this product inconjunction with a K&N 77 Series Cold Air intake. Not sure which gives me the instance response with the gas pedal and power to the rear wheels but when it is raining outside an you apply just a little to much gas and my tires are spinning.
5 out of 5 stars Totally surprised! - 10/07/2007
Review for: Black High-Flow Mass Air Sensor
From Michigan Reviewer: From A Customer   Own this product - Yes
This product seems fantastic. I put it on my 1999 Suburban two months ago and wanted to get a good feel of the product before I wrote a review. Previously I installed the Air Raid Throttle Body Spacer to my engine. Now after adding this Mass Airflow Sensor I have a 3 MPG improvement. Hard to believe I went from 12.5-13 to 16.7 mpg with hiway driving. Throttle response and power are better as well. I am glad I decided to give it a try.
