Yes please get rid of the MS CAI. My fuel trims are so much better now since I switched to Cobb. Also, no more violent hesitation at WOT. The MAF housing on that MS CAI is not fabricated correctly and has no air straightener which becomes even more important when you add a turbo inlet pipe...

Thanks amilliems6, I appreciate your response. Ulitimately I'm just trying to make my MS6 as fast (and fun to drive) as possible and I do see an opportunity for improvement with the intake temperatures. I received a response from CPE stating that the MS CAI is known to cause problems with...

For where you are located in Michigan, I would not even hesitate to switch over to the Cobb SRI. I think you will be happy with it and you won't have to deal with the dirty filter issue. When I removed my MS CAI, I couldn't believe how beat up my filter was. I even had the Injen pre-filter...

OK for example tonight it was 47 ambient outside temperature in St. Louis. Per my Dashhawk the IATs were around 100. With the old MS CAI they would have been around 65-70 degrees. Last weekend we had upper 70s, and my IATs were up around 120 degrees. With these higher IATs I don't notice any...

I don't think you read my post completely. I said the Cobb SRI seems to work better than any of the CAI systems.... obviously I know what a CAI is. I had a Mazdaspeed CAI for two years. It is not consistent with MAF readings and created a lot of turbulence especially after installing the CPE...

I've been wondering if any company (or individual) is designing a cold air box or some sort of cold air ducting for short ram intakes such as the Cobb SRI? I think many people including myself would agree that the Cobb provides more air and more consistent MAF readings than any of the cold air...

I cut the angled tips off my Magnaflow CB and replaced with straight tips. This elimated the rattling on the bumper. I also added a resonator pipe after the DP to quiet it down a little. I'm happy with it now.

Without data logging it's hard to say exactly what is causing this. With a catless TBE and CAI you are probably running too lean and the ECU cuts fuel to protect the engine. I was having similar problems and switched from MS CAI to Cobb SRI and the problem went away. You are really just...

The CPE tapers down to 2.5 inches where it mates to the stock turbo inlet. I haven't had any problems and I like the quality of CPE: includes stock mounting tab, metal vacuum nipple, and stronger metal sleeves that don't bend. I will agree it is a tight fit next to the battery. I had to bend...

I've been using my TurboXS hybrid for over a year and it works perfectly. I'm using all 6 washers. I don't think revving the car at idle is really going to prove that the BOV is 100% working or not working. You are not really creating boost pressure in that situation which is probably why you...

Turbo-back exhausts do not create back pressure... they reduce back pressure. This sometimes causes the turbo seals to leak a little oil (usually at vacuum idle) which causes the smoking. I've heard full synthetic oil smokes more than traditional oil. Catless TBE are worse because no Cats to...

Where are all the AP maps located? Where are you guys getting your Speed 6 AP maps? The main Cobb website only has a couple stock maps and a stage 1 SF map. They have everything for the Speed 3 and just about nothing for the Speed 6.

Yes the CPE Nviscid inlet pipe works with all intakes. You specify which intake you are using when placing your order. CPE will provide the appropriate connector based on your intake. The CPE Xcel intake uses a 3 inch metal sleeve connector. All other intakes including Cobb use a 2.5 inch...

CPE is designed better than Cobb I have the CPE inlet pipe and it fits fine without any modification to battery tray. Also, the metal fittings are thicker and don't bend when you tighten them down. The CPE pipe also comes with the stock mounting bracket and a metal vacuum line nipple... not...
