K&N filter, drop in or whole set up?

[2010SHOtime]

Hi all, I apologize if this has been talked about before but I just wanted to see if there is more of a benefit to go with the whole K&N set up or can I get the same gains(if any is to be had) with a drop in filter into the stock setup? Other than looks is there a performance benefit?

Thanks for the advice!

No real world performance benefit  with the Full K & N  CAI ... K & N drop in filter is a good option and many like it .

Most Folks go with the CAI for the eye-candy appeal and cause it sounds cool cause you can hear the turbos spool up better , same with AirAid .

I'd say, based on testing I participated in... that you could just use the stock airbox and filter for optimum performance.  I know the claims made from all the main manufacturers (albeit NOT with a 2013+ SHO).  Here's the data I have:

On the day when 4DR and I used my SHO (stock tune) to test 3 sets of the PPE downpipes on the dyno at Black Market Racing/Full Race (catted, Non-catted, and thermal coated catted)... (9 pulls-3 per set) ...We also did the following... in one pull we completely disconnected the OEM airbox from the intake tube (the saxophone tube going to turbos) and set it aside so we just had the tubing and no filter or CAI. We had the hood up, a big cooling fan on the motor, and back to back dynos with the same operator. temp was 79 and humidity was 30%

Result... less than three HP difference (same forTQ) between OEM CAI and filter and no filter or CAI at all.... 2-3 HP is not a significant change and lies within margin of error.  I believe that any restriction to air flow in the SHO is after the filter.  We know it can use more air than it does bone stock... we got 17HP increase with the PPE DPs over stock DPs with or without the CAI/filter.  Currently I believe the stock CAI and filter can deliver all the air the engine can use.

If you want some more sound from under the hood or like it as eye candy... go for it, nothing wrong with that.

But currently I can't personally recommend anything over the stock box based on the data if performance is the issue.

If you want better filtration try another filter. I hate oil filters... I bet you will too, hassle and oil gets where it shouldn't.

That's my 2 cents... sorry to seem like a rant.

I agree with Tom except that oiled filters have always worked fine for me.  I've used them in at least a dozen cars over the years.  Never the hint of an issue.

Thanks guys, that's a lot of great info! I figured there wasn't much HP to be gained but wasn't sure if I'd get the same spooling sound with just the drop in vs. The full setup?

[DJE624]

I guess I should add that I didn't care for the sound of the turbos spooling with my Typhoon.  It was kind of raspy to me.  But I do have sensitive ears.

The stock airbox dose a good job of keeping the noise down, i dont think you would hear the turbos much with just a drop in filter. I was going to do the drop in on my car but came across a deal i couldnt pass up for the typhoon (thanks DJE =]) . I love it, i have noticed the tubos are alittle raspy like DJE said but its only when under lower boost/easy driving. But when you put your footdown and start making some good boost the rasp goes away and they sound great!

Another CAI thread.....

K&N drop in filter. Apply $250 towards parts that will actually make your car go faster. /thread

Thanks!  I'm actually glad you noticed what I was talking about.  It was the same in mine under low boost acceleration.

I have tried both the drop in air filter from  k and N and now have a typhoon. The drop in does not sound any different from the Oem filter. As for performance I did not feel any seat of the pants difference. For the Typhoon performance remains the same however the noise fluff with it is pretty great IMO.

Thanks guys! A lot of great info and I think I'll wait a bit and just go with the entire setup instead of drop in.

I likes the noise the Typhoon makes.

I have the K&N drop in panel filter with a slightly modified stock airbox.  So I get the intake sounds like the Typhoon or Airraid for just the price of the panel.  I did this by making a 4 by 3 inch opening down low in the fender/headlight well side of the airbox.  So I still get the benefits of cold air from the front via factory intake tube and less restriction than sealed stock airbox.   I also opened up the radiator valance where the stock slit for air comes in (about 4x larger) and cut the the weather stripping to open the air flow at the edge where the hood comes down.  A little ram airish...  Some people like to spend money.

I did exactly the same thing - I used PVC drain pipe to plumb from the hole in the airbox to an area in the inner fender that is open to outside air.
