View Thread: K&N filters.. any good?


Carlos Carrera
Ok my sis has a 99 Jetta... (the 2.slow version) and she want to buy a KN filter, a sportchip, and Nology Cables.

i keep sayin' to her that the sportchip is useless for a NA car, and the Nologys too.
but what about KN filters? are they good ?

Might give a bit of 'intake howl' but that is about it. Unless you are keeping the car for a long time and then it can be cheaper than changing the filter multiple times.

Combined with an exhaust, maybe maybe you would get 7-10 hp but I don't know.

And I am guessing the chip will not do much more than raise the redline a little.

the drop in K&N filters aren't worth much - I wouldn't bother

I got a K&N for my car looking for some fuel savings, and I did get a small gain in that regard, which to me is worth it given gas prices--the filer pays for itself just in that regard. I can't say that I noticed any difference in performance, but I wasn't really expecting one.

I was under the impression that chipping some of the VW's does actually net you some ok gains. I know a girl who has a Passat who was waiting for a chip--I'll have to ask her if she thought it made a difference.

Really I don't think the 2.0's are that bad compared to their competition. I believe the 2.0 Jetta had what, 115 hp? Which doesn't sound like much, granted, but it was up against a Honda Civic who's base engine had 107hp I think, and definitely felt gutsier than the 127 hp version of the civic engine. It also handled better than a Civic (this was in 99 when the new jetta style came out I'm going by). At least the VW engine actually has MORE torque than hp. W/ the civic I think the base model had 107 hp and whatever torque--103? Something like that, and if you went to the 127 hp version, you only got ONE more ftlb of torque. So the VW engine actually has more torque than the 127 hp Honda engine. People forget that cars like the civic are supposed to be its main competition. Instead it gets compared to Accords or Camry's, when really those would be more the equivalent of a Passat in the VW line.

If your after performance, and if this will fit on a Jetta, the Apexi filter is hard to beat.

I put one in my offroader but it didnt do much that about 1 or 2hp. You dont have to change them as often so thats a plus. Other than that dont bother

She's interesting in buying a bunch of "mods" that won't do crap for power.

The VWs that actually benefit from a chip are the 1.8t cars. The reason is that turbo boost is controlled by the computer.

A chip is a waste of money on almost ALL stock NA cars. The only ones I've ever heard of gaining decent power from a chip are Bimmers.

If she wants more performance, tell her to buy none of the above. It'd be easier to trade her car for a 1.8t one

You'd be surprised what a difference it makes on the Tahoe. Mostly because the shift firmness, and updated shift points, I'm sure...but it's unreal how noticeable it is accelerating.

mustangdriver
I was planning on getting one for the GT soon. It's pretty cheap, lasts a long time and may give me a few extra ponies. I figure I might as well.

Sia Bani
Oh, I'm sorry...I forgot to mention...I was talking about the chip on the tahoe....not just a plain filter. A plain filter will do almost nothing.
Regarding the filter alone, you have to get a FIPK from K&N for the filter to have any signficance. I now have at least a 3mpg increase, and the performance difference on the tahoe is amazing. The sound rocks too.

Will, just a filter or the intake?

mustangdriver
I was just going to get the filter, but I'll check out the intake as well. :cheers:

yes, that was i told her. Chips are only good for the 1.8 turbo engine. But it worth it in some other cars, mostly with big engines. The filter is only good on the high RPM, but is not notable.
I know all of that, but i want to corroborate the info. Tanx

If yours is like the 2000 GT (like my brothers), I'm pretty sure it already has a cold air intake (into the side of the car).

There's just a silencer in there that covers most of your filter. Take that out.

Also, have you done exhaust on the car yet, or do you plan to?

mustangdriver
Exhaust will probably be the first big thing I do. Can't decide between the cost effective choice (Flowmaster) that sounds great or the more "exotic" and more expensive choice (Bassani). That probably wont' happen til after summertime with all the expenses that I've been seeing lately. In the meantime I'll probably do some small stuff (like the filter).

dude, put in the flows. Not the best performance, but the best sound. There won't be that much of a performance difference between that an the bassani....

mustangdriver
Yeah, that's what I've been hearing. There is a significant price difference too and the flows sound awesome.

Sia Bani
Get a 40 series and you'll hear it from 6 blocks away.


But what you should definitely do is have the muffler guy put on various series' flows and you can decide what you like. If he's not accustomed to doing this type of test, a) you should go somewhere else, b) you should tell him that all it's comprised of is him holding the muffler in place, while not welding it...just holding it in place with a towel. Then, he can have one of the other guys, or preferably you...hop in and rev it up.

mustangdriver
I had not heard of that before. I like it! :cheers:

Sia Bani
Ya, while you're there...be a bitch and have him put on whatever else he has....I mean, with the economy being shit and all....he is trying to sell you his product.


So put on the magnaflows...if you love the sound as much as the flows, which I doubt....but you should hope you do...get the magnaflow. Then whatever else you want.
