I have an HKS Sequential Blow Off Valve fitted on the car along with an HKS Air Intake. Everything has been working fine since i bought the car, BUT.....

I was looking at the engine bay and 2 rubber 3/4mm pipes caught my eye as they were hanging loose from the BOV. They have a thin rubber disc on the end of them also, so because there were two, it looked like they should be connected, and guess what.... they push-fit together perfectly.

(when the car is running one of the pipes is sucking air, and the other doesnt seem to do anything!)

But since i connected them the BOV noise is now a louder HISSSS rather than a quieter (butterfly valve) noise.
And on idle the car is struggling and kinda sounds like it wants to cut out.

Please Help Guys...
Thanks.
Ask any questions.

post pics of them.

One pipe come from the back of the BOV


The other pipe goes to here

thats a filter for the BOV refrence source.
you can remove it, and splice the 2 lines together.

Thanks presure2, can you explain a little more. Remove the smalls discs and splice pipes together?? Do they need to be joined at all? (bacause up to now they havent been)

And what is the BOV reference source?

Sorry for being such an engine newb!!
