Did a routine check-up on the Saturn tonight, and the air filter appeared rather dirty. Since I had forgotten to write down the mileage when I last installed a new air filter, I decided to go ahead and replace the filter with a new Wix one from my inventory.
The old filter was a Fram air filter. Just the normal Extra Guard, not the Tough Guard. The Fram filter had a lot more pleats than the Wix one, possibly twice the number. But that wasn't the concern.
With the airbox cover removed, the Fram filter fits snugly in the box. You cannot move it from side to side. But with the Wix filter, you can wiggle the filter about 1/2" from side-to-side.
Of course, this is all a moot point because the Wix filter still seals properly. However, I expected the Wix filter to fill the airbox completely like the Fram did.
