Negative Positive
Title: Great with a few simple flaws
Review: First off K&N; does not list compatability with the 2007 Cobalt SS/SC, however all three years of the car's production (05-07) use an identical intake system and it will fit the 07 model. The car gets a high RPM whine with a noticable increase in low RPM boost. Likely due to the removal of the restrictive bends in the stock intake.A common problem with aftermarket intakes is a Check Engine light (for too much air entering the system as would be the case with a leak in teh stock system) which i have NOT experenced. K&N; has changed the initial design of this intake and chances are they corrected the airflow readings of the mass air sensor keeping them within spec.The lack of 5 stars comes form a VERY tight install. It can be a rather large pain however with a little work it will fit and is one of the best constructed/clean looking intakes I've seen for the car.
Is the review positive or negative?
