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.

Near OEM quality at 1/4 cost
Near OEM performance at 25% of the cost! Bosch Quality replaced NGKs/Toyota OEMs. Great value and now the engine is running smoothly! I have seen a slight improvement in my mpg @1mpg overall in mixed driving conditions.

Very Expensive
Had one cylinder misfiring so replaced coil and spark plug. Runs fine now, but old plug looked shot after only 5 months so I think the coil was the problem. Really good plug so far but very expensive.
