Surprise!


Someone has put an aftermarket filter (K&N?) in . The orange hose is a poorly installed gasket that is supposed to go around the intake pipe entering the box.

The air box is open on the top - maybe it seals a bit with the engine cover? I removed the hose clamps and found that you cannot remove the air filter from the box - the filter is too big to get out the top. I think the box would have to be loosened up.

I'm interested in what it would take to go back to the stock configuration. What do you guys think? I can't believe this setup is better than stock.

The previous owner installed an Agency Power Cold air intake system. The split tubing is vibration dampening and acts as a seal around the MAF Tube. There was supposed to be anther piece around the top, to seal the top to the engine cover. The filter is washable similar to a K&N filter and may be oils to catch dust or not oils if you believe that oiling the filter ruins the MAF sensitivity.
