I just installed a K&N air filter on a 2012 Volvo C70 T5. The results were impressive.

Smoother acceleration. Quicker, more responsive turbo boost. A solid 10% more power by feel, before vs. after.

Best news: It was averaging 22.1 mpg before the install. It is now averaging 24.4 mpg, six weeks later! Amazing!

Best 42 bucks I ever spent.

I just installed a K&N Apollo on a 98 Volvo V70 2.3 T5. All I have to say is awesome! For the first time since we got the car you can actually hear the turbo working sucking in small children and such things! You can even hear the waste gate working when you take your foot off the gas! It feels like there is a whole new engine under the bonnet and the whole car feels like it has a massive rocket booster even with a full tank of fuel! THANK YOU K&N!

I tried the kit 57S-4000 with exchange filter from K&N with the new lid for the air box. Just looking at the product and thinking about the idea of putting in a bigger filter by making a new bigger lid of the air filter is in my world is brilliant. The work putting it on was super easy and with good fittings, and with an easy manual. The performance was noticeably better through all the revs. And the best part of all was that the fuel consumption went down below the car manufacturer’s data. This kit cost a lot, but it really works and it will save you fuel, and by the time it will actually pay it self off. I recommend this K&N kit to all Volvo V40 D2 owners.
