K&N Filters

Fuel Economy
Fuel economy testing and mileage claims are a tricky business. Just ask the EPA, whose website states, “EPA’s fuel economy estimates are designed to allow consumers to comparison shop. Your fuel economy will almost certainly vary from EPA’s fuel economy rating. This is based on a number of factors, such as weather, road conditions, your driving and maintenance habits, and your use of air conditioning.” A lot of exaggerated claims are made in the marketplace by products claiming to improve gas mileage. K&N makes no general fuel economy claims, however we encourage you to try our air filter for yourself. Keeping air filter restriction as low as possible can be an important tool, among others, for maintaining high mileage.

Also you said that K&N filters are suppose to give you "power that can be felt," but K&N states, "Our automotive OE (original equipment) replacement air filters generally add 1-4 horsepower." So I wouldn't call 1 HP something you can "feel."

By the way, how old was the Avalon and how many miles did it have?

Yes, I've never seen any Yaris owner post about thinking of getting a K&N filter, or just installing one, and asking what kind of savings will they see and how much of a HP gain is it worth ...and never read it here, even on this thread?, where a Yaris owner wrote that they can feel a difference after installing a K&N filter... I don't know why THEY think they can feel the power and expect to see a good savings at the gas pump ...like I stated before, they're a nice sound mod, and you can re-use them :)

Don't remember exactly on the Avalon, sure wasn't a beater; fairly late model (I do rembember that it was OBDII) and appeared to be very well taken care of. Main thing about the Avalon was that the MIL was on, couldn't get above about 55% calculated engine load @ WOT on the datastream, and had fresh oil buildup on the sensor, not the typical gray/tan dry ash coating that I come across.
