    Hello everyone. I took delivery of a 2013 Prius few weeks ago and I love it. My first mod was the shark fin and that wasn't too difficult.

    I am interested in getting a drop-in air filter, but I don't like K&N. Has anyone used HKS or TOMS before? Thanks for your inputs.

    An after-market/performance air filter will do nothing to help performance. The Toyota one works just fine.

    Congrats on the new ride.
    I have to ask: Why don't you like the K&N filter. I've used their filters for a long time and never had any complaints. People's mistake is over-oiling them. That's when MAF sensor problems show up. Not too many filters out there are made as well as the K&N.

    I don't understand the purpose. Yes, I've heard about MAF sensor problems as a result of K&N (which they deny, but that's a separate story). The stock filters air box work just fine and are on the VAST majority of Priuses... Never had a MAF sensor prob on my now over 7 year old Prius after 70K miles.

    I'm sure there are other Priuses w/WAY more miles w/no MAF sensor problems on the stock air box and filter.

    . Certainly nothing wrong with an OEM filter except expences.

    That's quite true. My primary concern is cost saving in the long run, and performance is second. Replacing disposable air filters with washable ones help the environment. That's my theory.

    The cost for conventional air filters is minimal. I doubt you'll get any significant performance gains. And, if you kill your MAF sensor, your cost savings are totally blown.

    If you really care, perhaps dyno your car before and after. But, the runs will also likely kill any cost savings.

    Anyone else is running K&N filter in GenIII? | PriusChat was an old thread on K&N...

    I bought a car with a K&N. Took it out. Held it up to the sunlight. Saw lots of pinholes of sunlight shining through.
    What do you think that means?
    You can reverse blow out a paper filter many times.
    You spend 2 minutes under the hood replacing one.
    How many products and how much time (making a big mess) will you spend dealing with "reuseable" filters?
    You will never be able to measure ANY performance gains.
    Compost/Re-purpose your old paper filter if you want to be Green. ;)joking
