Recommended replacment Air Filter

Discussion in 'General Motoring' started by Jason Russell, Jun 7, 2007.

  1. I have read reports that replacing the stock air filters can improve air
    intake and help engine performance and efficiency.

    Looking at the K & N website, the only air filters to suit a 1998 V70 seem
    to be either for the TDI or Turbo Petrol engines.

    Does anybody know if they will fit the standard petrol engines as well?
    Mine is 10v 2.5.

    If not, can anybody recommend another air filter manufacturer?

    Thanks in advance

    "Performance" air filters are a gimmick, use a stock Volvo paper filter,
    it's the best you can do, seriously. Someone recently did flow testing of
    filters and found the drop across a paper filter is negligible, someone else
    did a comprehensive evaluation of filtering and the performance filters let
    by substantially more crud.

    I've always felt it was better to replace an inexpensive paper filter often,
    rather than an expensive after-market filter seldom. I put a new STP or FRAM
    paper air filter in each year, just before inspection time (about 10-12,000
    miles/year), about $6-8 depending on where I get it. I also replace the 4
    sparkplugs (another $8) at the same time, and clean and re-gap them at about
    5,000 miles. Just did both jobs this afternoon, total cost was $17 and about
    an hour of my time.

    Don't bother. Keep a fresh Mann or Volvo filter in there and stop
    worrying about it. Few of the claims of increased performance with
    fancy air filter swaps are verifiable. Volvo uses a well designed air
    intake with a nice large filter area.

    Those sites are full of anocdotal reports but none of them offer solid
    independent testing to verify such claims.

    The obvious downside to such free-flow filters is that they will
    introduce a lot more abrasive contaminants into your expensive Volvo
    motor. Just buy Volvo filters or a good quality aftermarket like Mann
    and enjoy a car that should run for a very long time.

    Yes, either Volvo or Mann.
