Yes $500. It's more expensive , but the cost is justified because of not having to buy a 335D tank, dealing with splicing wires , and having crappy brackets and labor wasted having to do this twice.

That engine bay picture of Roberts kit is my car. I haven't had any issues since install. Everything went on smooth and I installed everything in my garage using hand tools and Jack stands. The install was self explanatory. I ran everything to my liking and away from all moving parts. Robert recommends relocating the vacuum canisters behind the Intakes next to the windshield fluid reservoir, but I relocated everything by the brake booster and the cowl covers everything and looks oem.

And I beleive someone asked about the 90* elbow for the pcv system and yes it was included in the kit. Comes with clamps to clamp it down onto the pipe.

And as far as the pcv hose goes, yes the hose is long and worked, but I wasn't happy with it being little kinked, so I went to home depot and built myself a 90* elbow so the hose can stay as straight as possible due to not wanting any pcv issues which means smoke..

The bracket issue has been resolved (current brackets will work, it's just a tight fit). Our kit utilizes the OEM tank. Splicing wires takes a couple of minutes and we will have the wire harness available for purchase in the next month or so for those who prefer plug and play. All that for $200 less than the opposing kit.

Heres the gains but doesnt show psi or anything, just the dyno curves. Would be nice to see if the gains were from higher boost or holding boost longer or what.

Also, this is gonna be pretty much the same for any of the aftermarket inlets.

I am still curious why some choose PR inlets over others like VRSF or MMP

Same reason why some choosing hexon over the other guys, despite not having to many reviews

If I already didn't have mmp inlets, I would definitely rock some PR inlets.

1) It is 1 piece, less chance of leaks. Granted it is under vacuum and not boost.

2) Should flow very well given there are no couplers which would in theory create turbulence. This is probably a moot point as all of the inlets are significantly larger than stock with significantly smaller choke points.

3) Was on pure turbos which currently dynoed the highest. Any inlet would of probably done the same, the fact it was the highest HP was because of the tune.

4) The fact it comes with the lengthened & prewired with connectors and you don't have to splice anything may be appealing to some. Some people get all concerned when talking about splicing wires(it is easy).

5) Nice brackets, something VRSF is fixing.

none of that stuff 'really' matters at the end of the day imo. but all of the small things might add up to a person and be enough to sway the buyer.



One question I have is there a difference in induction noise between silicone and aluminum intake piping. One quieter than the other?

I'd imagine silicone being quieter with less resonance/reverberation. But I have not heard them side by side.

That is my thought as well.

If that is the case another reason to purchase the kit. Unless of course you want the car even louder. Everyone already says inlets make the intake induction noise much louder vs. stock.

I was referring to the "sound difference" between silicone and aluminum.
