Ordered a used HKS RS intake system that needs new couplings.

Was wondering if anyone knows the size of the 3 HKS RS intake couplings, and looking for opinions on the best place to order them. Would measure them myself but it is not here yet and would like to order ASAP.

 

I assume you mean 4 couplers...just measured mine for you:

There are two reducers that join the filters to the pipes, size ID 2 3/4" to 2 1/4" (2" long)
Then the two straight couplers that join the pipes to the intake, size ID 2 3/4" (2 1/4" long)

I always purchase from HPS - Manufacturer of High Temp Reinforced Performance Silicone Hoses , Aluminum Tubing & Stainless Steel Clamps

Should have put a picture since there are so many versions up sorry.

Looking for the RS version, the primary filter bolts directly to the turbine, only has 3.

 

Hmmm,

Thats the exact kit I have...i just have not installed it yet....it looks liek they sent me an additional reducer.

So the sizes i quoted should be correct, you just need one reducer not two.

You could probably contact ZoomZoom also to confirm. I think he has the RS intake, and it looks like he is working on fitting it now also.

 

2.75 (2 3/4)" to a 2.5(2 1/2)"

That was the size I used for a replacement.
