I have been performing a lot of tune up/maintenance on my 1987 Volvo 740. It has near 200k miles and I'm owner 3. The previous filter didn't look trashed, but replacing it with the K&N did seem to let it breathe/rev easier. If there's anything wrong under the hood right now, it certainly isn't the air flow. I look forward to seeing if it's truly a reusable filter. THAT'S why I purchased, and I look forward to updating my review.
