Specifically designed and tested for the Mazda MZR DISI 2.3L turbo engine*, the CorkSport DISI Silicone Boost Tubes are made from six layer silicone coupler that contains five layers of reinforcement for a strong yet flexible connection that will allow for ideal flow into and out of the intercooler.

The CorkSport Advantage:

  • Custom formed for perfect fitment: The CorkSport DISI Silicone Boost Tubes have been designed to be a clamp-in replacement for the stock non-reinforced rubber hose
  • Six Layer Silicone Part: Contains five layers of reinforcement for a strong yet flexible connection that will not deteriorate over time and crack like the conventional stock rubber hose
  • T-Bolt Clamps Included: The boost tubes include 4 correct sized t-bolt clamps to make the installation look great and match your other CorkSport brand intake components.
  • Available in four color options: Complete the look of your engine bay by matching the hose color to your CorkSport SRI silicone connectors and boost tubes
  • CorkSport Service and Support: Receive full color installation instructions, all of the needed installation hardware, and knowledgeable telephone support

  • *Does not fit the early model Mazdaspeed 6 with the early cold pipe design.

4 stars rather than 5 due to lack of notes/exceptions for very early models and the cost. I don't usually whine about the latter, and although the tubes are very nice, there was an ouch factor for me.

If you happen to own a 2006 or maybe 2007 MS vehicle, check what style of intercooler to throttle body pipe you have (the cast aluminum pipe coming off the intercooler outlet). Early models utilized a 90 degree bend and a straight tube between the aluminum pipe and throttle body. Later models moved the 90 degree bend to the rubber tube and used a straight aluminum pipe.

CorkSport's tube is the one with the 90 degree bend.

I decided to order the newer style cast aluminum pipe from Mazda rather than cut the CS 90 degree tube for two reasons:

1) I measured and did a stare 'n compare, and I wasn't confident there was enough of a straight section to be had from the 90 tube. It probably works, but I've been through a few rounds of boost leak testing, and you'd be amazed how connections that look and feel 100% perfect leak air.

2) The newer pipe and tube design allow for easier removal of the intercooler (no wrestling with that 90 degree pipe, just loosen the top clamp on the boost tube and pull), which is why I believe Mazda changed the design.

Finally, if you look at some schematics online and think the CX-7 intercooler to throttle body pipe will work, it won't. It looks identical and seems to fit perfectly, but the BOV location is different and it won't allow the hood to close with the BOV installed.

Hope this helps the 6 people in the world who have the old style plumbing. ;-)
Great quality and instructions. The larger elbow required some cut to fit technique but thats easy as you just line up the OEM piece, slice and done. Also assuming thats b/c there was some slight variations in the Speed6 production years.



Overall, they do just what they're supposed to and install was easy with the instructions, even for a mechanically declined individual such as myself.
Easier to install than the directions imply. You will definitely need a deep socket for the clamps. Look and sound great. Strong constructions holds extra boost.
This pipes look great and also helps maintain power beyond 5500 rpm. I went from 14.7 to 14.5 on the track
Installed these today perfect fit! Got them in blue love the way they spruced up the engine compartment
will these fit the upgraded tmic ?



CorkSport Reply:Yes they do.
Black ones look nice. Fits perfectly, Will ensure no boost leak for years to come.
Super easy to install, and gives the motor a good look. Way better than stock. Would recommend to anyone with a few extra bucks!
Extremely good product. Unfortunately the larger tube didn't work for my engine but I used a Dremmel and cut it down to the right size. Much better support and a superb product! :)
Although my stock boost tubes were fine, I wanted to upgrade them to these fine silicone tubes for two reasons: a) I could see how the stock tubes could collapse or expand under heavy boost, and these thick and nice looking silicone tubes were my number one choice, b) the recirculation boost tube was rubing against the CS SRI, and I wanted to strengthen it by replacing it as well with the CS boost tube.



Installation was a breeze, the tubes are better than any other brand I've seen, the clamps are way more secure and air-tight than the stock ones, and I can feel the more steady boost levels. The recirculation boost tube, although slightly different in shape than the stock one, has a curve that prevents any rubbing with the CS SRI.



Definitely two-thumbs up!

i have a pu with a SU tmic (yea yea i know, got a good deal, i would have preferred to have a cs tmic to keep the engine bay looking stock). the SU tmic doesnt line up correctly with the stock boost tube that goes to the turbo, thus causing a cut from the clamp to happen in the stock boost tube and due to the improper fitment is causing my synapse sb bpv to have those vacuum/boost lines rub on the hood.... my question... are these exactly the same size as stock or are they a tad bit longer than stock? or is there a way i could order the boost tube to the turbo slightly longer to compensate for the poor fitment of the SU tmic?

so i had a boot gauge installed and they had to cut into my boost tube to install the t-clamp. anyway i think i might have a boost leak. Will this replace the stock boost house ans fix my problem?
