no problem on me.. I can hear the "hissing" sound better!!!

 

hks drop in is great, but if your gonna get an AP i heard the Perrin AP is better with the hks drop in.

 

Dude Perrin and Cobb offer their maps for free!

 

i thought perrin only offers there maps free if you buy the AP from them(unless they changed it), but i know cobb offers them for free.

Perrin map was $150 if you didnt buy it from them

 

You are correct; Perrin will send their own map. COBB is working on maps and are suppose to have one for the HKS panel in the near future.

 

Loved it

 

i ahve sold to my customers over 30 of these units around the world.


top effort

 

I've had no problems running my HKS drop in air filter and Perrin Stage 1 tune.

The only thing I don't like about the HKS filter is the seal it makes with the stock air box. I wish instead of the hard plastic it had some sort of rubber seal.

 

agreed the hks drop-in is a little smaller then the stock one, so it looks like its not fitting correctly.

 

anyone using this have their maf go out, code p0102? I have it and just curious as a few others i have read had same issue.. 6k miles on car, about 3k on filter.

 

I had no problem with mine...
i even got a tune stocked with the drop in
and i had good gains...

We had ours on since we got the car, 10k later and a few track days, still no problem

 

I had to change to a ralliart filter as the HKS doesnt filter out the dust well enough here in Dubai!

HKS

The Good: Some gains, noise, and cheep

The Bad: Sand and dust in my intake!

 

can you wash these filters?

there is no way in hell i would listen to that guy on the above how to link.. did you see how much was left over oil on the corners in the plastic.. BY BY maf is all i can say.. The hks are 40 bucks for a reason (didn't know at first), you dispose of them and buy a new. =/
