Easy to Install - Good Value for the Money
This is my first experience with K&N engine oil filters. I purchased one through AMZN and it was cheaper than expected. I may have purchased it on sale, because it was only $10. K&N is known to have great products, so I will update this review after I've used this filter for a while. So far, it seems to be working fine.

Great plug
Style: Single
My car goes through these every 30,000 miles or so. But fantastic plug all around. Performs flawlessly even at almost 9000 rpm.
