I recently bought a 93 vr4. Has ran fantastic for the couple months I have had it and still does. But here is the deal....I realized that the air filter that was currently in it was very old and dirty, so I decided to put a drop in, k&n filter in it to help the car breathe better than that dirty old one. With the old filter, on a hard pull I was pegging 14lbs but now with this new filter, I am lucky to hit 8-9lbs. I’ve looked everywhere in the car and on the internet for an explanation and I am stumped. What’s going on?
