just wondering whats better K@N or HKS filter for a s4 getting the adapter just dont know what filter to get (cone/idk what the HKS is like a dome? lol)

 

If you're looking to get Carb approved so to pass smog (if that applies in WV), then K&N is your only alternative. HKS has pulled out of the states, so you can't get a replacement CARB sticker.

Either way, I personally like K&N.

 

best drop in filter!

dont get a cone filter unless you keep it away from heat. if u do. get a AEM dry flow air filter

Smog doesnt apply in our state. Where your filter will set and your n/a needs the heat also will not be an issue. Our vert has ran like that for years and years. no issues yet. Sydney, all you need is the adapter with a quality K&N filter.

 

Also with your power, and the fact that you still own the factory air box this ^^is a good plan. Probably cheaper too by the time you get the adapter shipped, and the k&n filter

 

no smog here. and im wondering which one has better performance value... i think the hks looks cool!

not getting a drop in tryin to go to a cone filter/dome w/e the HKS is lol

 

lol already ordered the adapter lol

 

and even if i was somewhere that i had to smog it wouldnt madder cause they wouldnt beable to find it lol if they did id say doesnt that look stock? with a $50 bill lol

 

I'd keep the stock air box and use a drop in filter.. But if your going cone style no matter what, k&n and apexi are quality filters. The HKS mushroom style filters might be necessary in some cases where space is an issue, but their filtration and longitivity is arguable. The foam element is supposed to be replaced often in them. If you never replace it, it can deteriorate.

 

For a stock NA 13B engine, the best performance value is from a high-flow drop-in filter like the K&N replacement filter. However, it sounds to me like you have already made up your mind based on looks rather than performance. There is nothing wrong with this, but you should not try to fool yourself or others. A pod type filter without custom ducting will suck in hot air from the radiator, reducing engine performance. This is mostly seen below about 30-35mph, so you will probably not notice the performance decrease unless you are drag racing your car. Fortunately, the increased intake air noise will at least make your car sound faster.

Anyway, I would normally recommend the HKS product for looks, but since you have already ordered the adapter then you may as well go with a K&N universal filter. If you want to retain the function of the air pump, then you will also need a "crankcase vent" filter for the air pump tube, which you will find when you remove your stock airbox. The HKS filter assembly has a bung for the air pump hose so that it can use the same filter as the engine inlet.

Yeah, that's a great way to turn a $75 non-moving violation into a 5-year prison sentence. Brilliant idea.

 

I didn't know HKS US was gone.. dam knockoffs and probably not enough support. I have a few hks products myself.

edit: maybe i dont remember.. just sucks the knockoff companies are doing strong but the originals are suffering.

 

he was kidding im sure...

and 5 years in prison, Missouri must suck worse than anticipated.

As for you Sydney, no one is going to care or **** with you about the cone filter setup, your going for a fun n/a setup. You wont have any issues due to the filter. Get it done clean it up, painted and sell it to fuel the fb tII build. Hell i might buy it as a daily later on.

 

what are the part numbers for the k&n intake? I got screwed when I bought my hks intake...having a hell of a time getting the carb sticker for it

 

yeah im familiar with the foamies i grew up riding dirtbikes so lol i understand...

i know about the ducting ive made real cold air intakes for a lot of my friends in vegas turbo and na its easy lol

haha yeah your funny haha

fa sho lol and im not sellin it lol i know you guys want it haha but im getting my bros vert ill let you guys get first picks!
