K&N (or other) Intake Air Filters

[TOGuy242]

Anyone else try the drop-in filters yet?
Gave my old Infiniti a meaner sound and maybe a little more on the bottom end. But the sound probably made it feel faster!

I've been running with the drop-in K&N filters since I got the car. Hard to say if it makes much of a difference - don't think the sound changes unless you do the full replacement air intake.

Basically the K&N (and presumably other) filters are made of cotton versus the paper that the OEM ones are made from - this allows greater airflow to the turbo (yes that's why there's two) which theoretically should give you a *slight* boost to power. Realistically so little you probably wouldn't really notice it. As an added bonus the filters are cleanable, and reusable, so rather than having to dispose of the OEM ones each time you can remove, clean, re-oil and replace the K&N ones over and over. It's a little more work obviously, so not for everyone. I had one in my previous 2.0T car for many years without a problem - in fact since I had an engine tune it was pretty much required.

A good explanation is on their website - K&N Lifetime Performance Air Filters - Aftermarket Automotive and Motorcycle Air Filters

The ones that are made for the 3.3 Stinger are about $50 each, so $100 for the set.

Any warranty voiding issues with running these? What do you mean by they sound better? Like the "whistle" you get with a turbo is louder?

Yes, there will be a loud whoosh from the cold air intakes upon full throttle. I just traded my 14' Taurus SHO for a G70 3.3T. I had CAI on the taurus and definitely got 1-2 mpg better fuel economy. As for more power, seat of the pants feel, is very little. But, on a 4300 lb car, 30 HP will be feel very slight.

So can anyone give a 100% if the Kia Stinger K&N Typhoon Dual Intake can fit in the G70 3.3T? Before i spend $500 CDN

I will throw my 2 cents in. You're better off saving your $ and getting yourself a JB4 or LAP3 tuner. Every video I have ever seen testing K&N comes back with insignificant (1% at best) increase or zero effect in power.

Yes. It will fit just fine. The heat shields, on the other hand, may need some trimming around the driver's side to make room for the OBDII connector by the shock tower. Also, if it's anything like the AEM intake (which it should be), then you may need to trim the diverter valve hose on the passenger side so it doesn't kink. I opted to get a whole new straight hose from Amazon instead of trimming my OEM hose.

I was actually thinking the same thing a real tuner is alot more beneficial but for some reason I just love the sound of the engine with the intake. I def would not be buying it for any HP increase

Thank you! I actually saw even on a Stinger a guy on youtube had a kinked hose he left it kinked -_-

Honestly if you left it kinked it wouldn't really matter. Those are only the diverter hoses, so they don't really serve a purpose other than it blows the charged air into the intake elbow, before the turbo, when you let off the throttle after you've built boost. You could even just disconnect them and let them vent into the engine bay. You'd have to plug the holes on the intake elbows, though.

Speaking of sound, the AEM kit (which is identical to the K&N kit, except for the filters and the elbows are plastic instead of metal) makes the intake sound AWESOME. You hear the turbo's spool really loud, and you can hear the diverter valves "whoosh" when letting off the throttle. It's sweet! Definitely can make driving even more fun. In addition to this, there really is a power increase. Stinger owners have said they measured a 0.2 second improvement in 0-60 times with an intake alone. Dyno's consistently show around ~25WHP increase. Of course a tune (ie JB4 or Lap3) make a MUCH bigger increase in power, so may as well do them both! Haha.

Thank you everyone for your thoughts! I'm still so stuck on the fence between "this is a luxury car I dont need the intakes" and "this is a fast sports car I want it" I may go with the K&N because it's on sale right now for $499 CDN which is a really good price original $649. I dont know what I would do without this forum this place is great!

I'd go with "it's a fast luxury car".

P.S. - And get the intake!

If you are actually interested in comparing flow between oil fused filters and the more normal paper filters do a little research on Google. A Independent company in CA tested all the name brand elements in a controlled enviornment. The K&N that folks here seem to think it is the king, but it lost to AC Delco brand paper elements in all forms of measurement. The K&N allowed more dirt thru and less airflow than the winner of the test (AC) but it also lost to some other brands that most people recognize but never consider buying, and none of them were oil coated.

I found a few articles showing similar results over a decade ago. I was a die hard K&N fan before this. Afterwords, I held up one of my K&N filters to a light and was surprised you could see tiny holes that the light was passing straight through.

In addition to this, there is info showing that more filter surface area makes a bigger difference on flow than the material type itself.

Performance washable filters, in my opinion, are the way to go.
