    i used to have an open-type filter by k&n paired with an iceman tube on my old civic with headers and muffler. the car is still fuel efficient as long as i don't floor the pedal that much.

    The effectiveness depends also on how restrictive your stock intake system is. On some cars it can be negligeable, while on others you really get instant results, especially when paired with a good set of headers/exhaust system.

    Usually i'd notice better breathing and acceleration in the high RPM band since the car gets to continue breathing better as the RPMs rise.

    On fuel economy, it'll depend on your right foot actually. If you enjoy the sound the filter makes at full throttle, you're gonna find yourself flooring a lot. :)

    The filter alone isn't much of an upgrade in terms of power. Use it with other modifications.

    However I'd justify getting one because it can be the LAST air filter element you'll ever buy. You don't have to throw it out---you can clean it and reuse it. K&N also sells the cleaning oil, and you don't really have to use all that much.
  • true. also the air filter alone won't make that much difference in terms of performance. overall k&n is a very good brand.
  • you cant really tell much of a diference in performance in using K&N's but I would recommend them. I am currently using the cone-head filter for my AEM cold air intake. It gives a bit of a boost in accelerating. Saves money as I do not have to buy it every time i change my oil heheh.

    FYI lang ha?

    Just in case you didn't know, K&N makes both cone-type filters (for use with aftermarket intakes) and drop-in filters (for use with your car's stock airbox, in case you want to keep it). Both are high-flow units and never need replacement.

    ... yup... you'll just need the cleaning kit (around P700-P900 and it lasts very long).

    To give an example, when i changed the headers of our B14 Sentra, i really felt the SOTP gains when i added the aftermarket filter. If done vise versa (filter before headers), it'll more or less be the same results as well.
  • Guys saan makabili ng drop-in filters? Been looking around and puro cone-type lang nakita ko. Ride is a '95 Lancer GLXi.
  • you can buy K&N air filters at FUSION R (one of the official distributors) it is located at E.Rodriquez ave. QC. near tomas morato. tel#7243921 look for ferman.

    or for exact part number log in to the K&N website for the specific part you want to find k.

    also, thank you guys for your inputs
  • Thanks! Got my part number na price na lang ang itatanong ko.

    You can also check the ff shops (aSide from Fusion R):
    - Pony Cars (Cubao Auto Centro)
    - shop next to Nodalos in Alaabang Motortown (across ATC)
    - Hans Tools Shangri-La.

    I won a drop-in filter before from the Tsikot.com grand EB... Pang Civic nga lang :P
  • Salamat! Kung di naman ganun ka-laki ang difference between an orig paper disposable filter and the K&N filter I'll go for the K&N for long-term savings.

    Ferman uses a K&N drop-in filter in his rallye/autocross City. His airbox has a sticker warning not to throw the filter out. Looks like it came with the box. :lol:

    Slamm: Sa ATC pala meron din? Would you have an idea of how much it costs? I might consider getting one myself, even just for the reusability factor alone.

    Yup... there's a sticker warning that comes with the filter. The B14 Sentra we bought last year had it on but the filter was missing (either kinuha ng owner or someone at the Nissan dealership got interested in it when the car was traded in by the owner).

    Yup, meron sa ATC. I bought my cone type filter there before at a good price (mga 2.6K)... I can't recall if they carry the OEM drop-ins though but they had a lot of K&N stuff on stock when i was there. It's the shop beside Nodalos (can't remember the name).
  • Just called up Fusion R and medyo may kamahalan din pala. Ipon muna ako hehehe

    A friend told me his drop-in filter for his EK Civic LXi was PhP3500...may kamahalan nga :( Add to that the PhP900 cost of the cleaning kit.

    Ipon muna...then again long-term naman ang gamit nya so it should be worth it in the long run :)

    Does the CR-V '98 share the same filter type as yours? Sayang, if only still had that new filter i had before, i could sell it at a lesser cost. :D

    It depends in how you defind it works, it works in keeping clean air going to combustion chambers, but if your asking if noticable in fuel economy and increase in power, I didn't notice any. I have it installed in all my three vehicle because I don't like to buy a new filter every year.
  • I had K&N filter from my last car and I have it in my current car. No noticeable power gain (even in high rpms) nor fuel economy. I have it for the sole purpose of my car breathing in cleaner air. Thats all.
  • pwede pa bang lagyan ng ganito yung 89 na 'rolla?
