Air Filter Question????

[naim amiouni]

Has anyone fitted his car with an air filter such as K&N or HKS etc...(performance filters). If yes wats the difference does the cars noise and performance differ??

[tydale3]

Just put in a K and N yesterday, once i read the DIY on how too remove the engine cover. When it says pull hard it means HARD!!!!!!!!!!!!!!!!!(scary).

Its a little louder, not much. seemed to imrove low end tourge if thats possible. Roll on power in top gear seems better too. I just like them because you can use it many times over. Way cheaper than buying new filters all the time. In my opinion the size of the intake tube to the turbo limits your air CFM anyway. Unless you mod the turbo and the Air tube too the turbo all those aftermarket intakes are a waste of money. Your performance is not going to increase enough to make a difference. Sound might , but performance with stay close to the same.

All around good info and points too!:thumbsup: :thumbsup:

Oooo... there's a K&N out for the GTI?

I'm a long time fan of K&N for the ease of use in what seem to be increasingly complicated airboxes. The Passat was one of the worst.

If you're trading up your bedsheets, keep one of the pillowcases around for cleaning and oiling time. Clean the filter as prescribed and let it air dry. When it comes time to oil, spray the filter down and pop it in the pillowcase. Swing it around over your head (outdoors!) and you'll escape the accidental over-oiling trap. :)

My Transformer's sheets are the skids, should I trade up to Smurfs or Spidey? Can we get a Poll started on this?

:smoking:

[Wild Hare]

Does SpongeBob qualify?

[Freek]

hrm...i cant seem to find a K&N filter for the MkV GTI....even K&N website doesnt have it listed....any idea where to find this filter?

[Call.me.Junior]

i'm also glad to hear k&n put out a filter for the GTI, i looked at their website when i got the car a little over a month ago and they didn't list the GTI. time to go shopping

[naim amiouni]

im just worried that if i fit my gti with an air filter the farting sound while gear changing will decrease or vanish.i really like my car's sound(especially the farting sound).u think itll change that sound???

probably not...cuz that sound is the added backpressure from the boost...its all exhaust sound...really nothing to do with the intake

this may help u guys

huhhh, 3 different part#s, which one is the correct part for our cars?

[GTI2007]

Those 3 different part#s you mention are adapters for the filter.

those cone filters are only good if u are going to run some sort of piping down into the fender or front of the car to get cooler air

im just looking for a drop in...i guess ill just get the GLI one

if I fabricate a custom pipe that runs down into the fender would this be a good option to use as a filter?

yup...cuz if u look at the filter u can see the inlet is actually made for a pipe of some sort to be connected to it

a normal cone filter is open so it gets air from the whole surface of the filter...these filters are incased in a heatsheild type of thing and the only way for air to get into it is the front part

No, No, No, DON'T DO IT...

yes you may get colder air but if you are not an expert with air flow you will lose so much more power from restricted air flow than you could possibly gain from getting air that's a bit cooler...


If you want a true CAI that benefits from both air flow and air temp wait for a company to make a CAI specifically for a MKV...

[HotLanta MKfizzle]

my buddy works at TAP plastics he fabricated one for his MK2 GTI, it was a rat, but he got good results on the DYNO. I don't see any of the major player's working on an intake that dips down into the fender, so I might have to try it out for fun.

[Freek]

Vivid is right...technicly those K&N cone filters are very restrictive cuz of the small inlet that the filter has

but as in the case with all pipes...be it exhaust or intakes or plumming pipes for your house

u are only going to get the amount of flow that the pipe will allow...so if u have an open filter but only a 2" pipe feeding that air into the motor it will only flow the CFM the pipe will allow...same goes for exhausts...your flow is only as good as the smallest pipe..doesnt help to have a 3" downpipe if your exhaust is only 2"...cuz u will only get the flow of the 2" pipe

so basicly what that means is if u were to get one of those filters...make sure u get pipes that have a decent diamater...the pipe going into the filter and the pipe coming out of the filter

hopefully that all made sense :biggrin:

but just to add one thing... I would guess that a 3" "Z" shaped pipe would restrict more air than an 2" "l" shaped pipe... and air flow is far more important to performance than air temp...

If you've got a friend who has made one before talk to him about doing one for yours and let us know how it works... You might have a good little business prospect?

aye very true...but as long as the pipe is mandrel bent or one of them flex pipes u can get from pep boys or exhaust shops...it shouldnt make too much of a difference if it is "I" or "S" shaped(granted u will have a little more restrictive flow on an "S" than an "I" due to bends)...But as long as the diamater is nice and big it shouldnt be a big deal

already said it once...it was in another thread...i dont use that work too much cuz people have no idea what it is...some think its "the" misspelled...others think the person is laughin when they write "teh"

when i use it tho i use it as the l33t! spelling of "the"

lol

Don't know that filthy pig-latin, try to keep it cut-and-dry for some of us guy's that actually see the sun once in a while.

[tydale3]

not sure , but i think the VR6 Gti is the same filter size as the MKV. I cant find the site where i bought mine now. I forgot to save it in my favorites. I think I remember when i searched for the MKV it acually came up as the VR6.

kool thanx for the headsup...some might wanna do this...as for me im doing a K&N drop-in

[rica_roel]

And offcourse, if is to low maybe on a rainy season your engine can breath water, not a good idea.

[Whafrodamus]

Has anyone installed the apollo yet? I'm really interested in getting it installed.

[ConnerrySER04]

I'd actually like some info on the benefits of the K&N drop in on these vehicles. It seems as if there is a decent performance increase on a turbocharged engine vs. an NA one. I tried searching and didn't come up with very much; any real world insight, anyone?

Once I get some of my musical instrument sales out of the way, I'll pick up the drop in air filter and the apollo intake. Be a test dummy. One oculd always return them after not being satisfied with results (Worst case scenario). I'm quite optimistic.

I know it's a decent mod just for the longer lasting, better flowing drop-in filter. That's decent for the $50...but if what I'm hearing is true, and the mod really nets another 6-8 whp, the it's a hell of a bargain at $50. I'll probably just bag it this weekend regardless, but it's be nice to hear some actual testimonials. There's a guy a few posts back that has it...I would mind hearing more from him (or anyone in the know) on the subject.

BTW there is no official listing for the GTI on K&N's website, but the 2.0L for the A3 and GLI all use the same part #...sounds like a safe bet.

Be careful on pipe placement. Have known several people who did their own and found out later on that the were taking water in when it rained hard.
