I want the HKS racing suction kit but do I need to worry about the MAF? Does it work with the stock one?

 

It uses the stock MAF.

 

yes, but on the dyno I made no more hp than I did with the stock setup. so I say save your money and use it for other stuff.

 

it does use the stock MAF but the most power will be gained by using it w/out the MAF & enclosing it in an airbox like the apexi or hks kansai. if i recall correctly HKS Kansai has gotten around 25-30whp w/ that setup.

 

I made 15whp with just the HKS RS intake and SSQ BOV.

 

the HKS kit also sounds wonderful. makes your stock turbo so loud people will think it's not stock!

just the HKS SPF filter i use fools people, but a certain shop owner thinks i'm losing 20whp for not using the APS CAI that he sells. i laugh at his silliness...

 

I have it and made power with it aswell, you can use the stock MAF.

 

does your car need to be tuned when you install a intake? I was told it is needed.

 

I have heard that some people after installing the HKS RS would get a bogging feeling at times. But then it is advised you get a flash so it will take full use of the intake.

I have heard very good results when you get a flash and intake.

 

I thought only when you want real big hp like bigger turbos you dont need the maf. Otherwise the MAF is necessary to retain stock idle?
