Mazdaspeed6 Cobb Turbo Inlet Install How To/Review
Overall Review
This is a really nice piece. It is reinforced so it is not that flimsy and can support some weight. Fitment of the intake on the metal sleeve was a bit tight but some lubricant can help slide it on. Also since the inlet is not secured anywhere except the turbo, it does move around a little when installing the intake making it a little tricky, but with some patience it isnt a problem. For the novice installer allow yourself at least an hour to install this, for the more advanced I would say this can be done within a half hour. It took me about an hour but I was taking pictures and pressure testing. Also if you have the stock turbo inlet there is a little more work involved. Overall I would rate this inlet very high in quality and somewhat easy to install for the more advanced modder.
Driving Impressions
Just went for a quick spin around the block and this inlet is much quieter than speedie6's inlet and I like it, no offense speedie6. I'll update this portion after I log a few more miles on it.
Tools needed
-8mm socket
-10mm wrench/socket
-12mm wrench/socket
-various extensions
-flat head screw driver
-channel locks
-wd-40 (used as lubricant)
Install
This install was not done on the stock turbo inlet pipe and some directions may vary.
Step 1
Remove intercooler cover and disconnect battery terminals (10mm)
Step 2
Remove battery tie down (1) 10mm nut and (1) 10mm bolt and then remove battery carefully.
Step 3
Remove battery tray by removing (2) 10mm bolts.
Step 4
Remove intake from turbo inlet, valve cover vent, and disconnect bypass valve hose using channel locks (it helped to remove the hose from the bypass valve and then from the turbo inlet.)
Step 5
Remove 10mm nut holding turbo inlet in place as well as the clamp (10mm t-bolt or worm clamp) holding the inlet on the turbo.
Step 6
Here is a comparison of the cob inlet, stock inlet and speedie6s inlet
Cobb Inlet alone
Install Cobb inlet on turbo and secure worm clamp (8mm), also connect boost control vacuum line onto plastic nipple.
Step 7
Make sure both metal sleeves on inlet are protruding half way out and then secure them with supplied clamps (8mm).
Step 8
Reinstall your bypass valve hose and intake (wd-40 used to help slide bypass valve hose and intake on to metal sleeves as fitment is a little tight.) Make sure all your clamps are tight and everything is secure, reinstall intercooler cover if necessary and you are ready to go.
