Bought this filter as an extra so I'll always have one ready to use... Been using K&N filters on everything I own for many years now with NO problems at all...

After installing this K&N Cold Air Intake (which was exceptionally easy) my Duramax started purring like a kitten. The idle just smoothed out. I haven't checked the mileage yet, but I'm sure it has been positively affected. I wouldn't buy any other brand.

Went together very easily but snapped one of the air return nozzles by over tightening. Probably my fault but that's what happens when you put plastic fitting into metal. Overall very happy. Throttle response really woke up.
