hi,i just changed my air filer with a k&n filter that I purchased from auto anything I was very pleased with that company,anyways there has to be a better way of doing this. oh well just thought I would add my 2 cents to this subject. have a good spring and summer. len
Somehow I did n't notice this when I installed my K&N filter but when I cleaned it I saw this and decided to clean it out also. I don't understand why they would put this material inside the air intake tube that runs from the box to the fender hole. I was figgrin' to help catch junk so it doesn't clog up the filter, but no other car I've had had this and the filter in these cars are not abnormally small so I dont get it. I think A smooth tube may help a bit, but I doubt you'd be able to see or feel any improvments.
Whats your thoughts on this?
From my experience, the wool tube resists heat to keep the air cooler going in for better combustion, BUT it is also breathable which leads me to think its also sucking in the hot air of the engine bay unless there is some science behind the use of the material ? Mine was torn up so I threw it away and still looking for a replacement tube but cant seem to find anything to replace it with?
The "wooly worm" design is meant to act as a pre filter.... Finding larger pieces of stuff stuck on it's inner surface has kept those pieces from being stuck in the main air filter. (IE Better breathing)
It's also more of an insulator than a metal "dryer vent" tube would be, keeping the underhood temps out of the air intake system. (IE Cooler air)
Subtle differences that would not be felt in the performance of the car by changing materials, but GM didn't use that setup without reasons.
Agreed, however the woolly worm is an expensive piece, last I was quoted over $125.00, that was ten years ago, and now that they are discontinued or close to it , the dryer vent tube works nicely, the Olds 442 had vinyl tubes to its twin snorkel under the bumper air ducts
air filter change.
