Does anyone know if there is any real difference (other than color) between HKS, mushroom style, foam, intake kits?
It seems like they have 2 main kits.
*Super Power (Mega) Flow-Green
*Racing Suction -Yellow
Then Greddy has
*Airnix -Blue or Yellow

Are some just older than others? Or for single turbo vs twins? Or are they all pretty much the same?
Thanks

 

I am no expert on the construction of the filters? if that is the question? but the kits you are speaking of include different styles of pipes, The Racing Suction for example includes a primary turbo pipe that bolts directly to the turbo housing without any couplers.

 

Taken from HKS website:

"HKS Filter Elements are available in a dry 3-layer, triple density or wet 2-layer, dual density construction. The dry 3-layer type is standard in SMF Reloaded Intake kits, and is designed for superior filtration while still providing excellent airflow. The wet 2-layer type is included in Racing Suction kits and is focused on maximizing airflow for performance, yet still keeping harmful particles from the engine. If your vehicle is in a high dust area, HKS recommends using dry 3-layer elements."

HKS Intake Kit $300+


HKS Racing Suction (RS) Kit $500+


Filter oil should still be added to perform efficiently. You can use K&N filter oil, or non-colored filter oil from motorcycle shops.

 

The rs pipes are polished and angle towards the passenger fender. HKS makes TERRIBLE filters, there are several tests showing HKS filters does a horrific job filtering. If you are going to spend that much money on the hks rs intake, I would buy the autoexe intake, which uses a k&n filter and looks 10x better.

 

Does anyone know anything about the quality of the Greddy filters?


Sorry about the thread hijack...

 

Yes that was going to be my next question.
And thanks for the previous answer.

 

Crap i had them on my FD because they fit with the greddy FMIC. The part that holds the filter was made out of plastic so it would easily break. Also i would stay away from Mushroom style filters and go with the cone style. It never happened to me but i hear the foam can break and get sucked into your turbo and that would be all bad.

 

Greddy filters are only SLIGHTLY better then HKS; I suggest either apexi or K&N filters.

 

Link, I love your engine bay setup... so nice.

 

Yes, its true. Apexi and K&N filters work the best. As long as the sponge type filters are oiled, they work very well. I've been running the RS setup for 4+ years now. the engine is still running strong and i love the way it looks.

Although if there's a K&N filter that will clear fit on the RS piping, i would change it in a heart beat.

thanks!

 

LOL, I swithched from K&N to the HKS I've always used HKS Filters and never did I have a problem with it...But in any case everybody has their like and dislikes...some people don't even run filters at all...LOL..

 

There is only one test and that test was copied all around the internet when it came out. That test wasn't even done by the writers of the information in which they even commented that it may be a stunt to get the lesser known intakes some of the market:

Read the closing:

"It is questionable how accurate the original source of data is, as HKS are proven to sell more induction kits than any one of the others featured in the test, and yet there induction kit rates as the worst kit in the test. This suggests that either HKS rely upon their brand name to sell their 'poorly' manufactured air filters, or that the original Japanese test was nothing more than a PR stunt to promote the lesser known equipment. HKS and Blitz continue to be the best selling induction kits in the UK, and are used by Middlehursts, Hiteq and Abbey Motorsport as their first choice when the induction kit modification is carried out.

One thing that does stand out is the fact that all the induction kits seem to offer similar performance gains, of around 13 - 14 bhp. This would seem consistent with actual power gains that have been confirmed by using a rolling road. "
