Volvo V70/XC70 2001-2007 » Air Filters (K&N)

Just dropped an #E-2019 in on my '04 S60R w/ 50K miles.

Pros, filter arrived quickly and came pre-oiled. Simple install, 4 screws to air box & 2 clamps on filter; took maybe 5 minutes in the parking lot. Car sounds a little bit more aggressive and you can hear the CBV a little more.

As for cons, I did not notice any difference in performance but, in theory, since it is louder I'm sure it is probably flowing better. I'm assuming it may let in more dirt as well as oil spray if I over oil the filter. Small dirt particles will probably just get vaporized but I'm thinking the oil could throw off the mass air flow sensor readings if too much gets coated on there.

Every time I clean & re-oil the filter I'll probably go in a few days later and clean the MAF which takes like 2 seconds. IPD also sells the MAF cleaner. Be gentle with the sensor and use MAF cleaner only! Anything else (like carb cleaner) may destroy your sensor.

Just another note, yesterday I ran down to the corner real quick to grab a tool and had left the air box lid off. The intake was WAY louder. With the lid off there is probably less restriction but all that hot engine compartment air is probably counter-productive. Sounded pretty wicked though =)~

k&n air filters may provide better engine breath but they also alow small particles to get into your engine! if you look at the filter up to light you can see tiny holes in it! use oem!

Always use K&N. better gas milage, save money on filters, and better performance. Not many upgrades do all at once.

Have used K&N filters in previous Volvos and this was a painless and enjoyable upgrade to the stock system. Provides a little throatier sound on hard acceleration.
