Heya,

So I wanted to see if anyone on here had run into this, and get some opinions or ideas.

I have a 2000 996 C4, love it. I bought the EVOMS cai, and installed it. I noticed while installing it the fitment from the filter to the pipe connecting to the throttle body did not have any method of being sealed. The pipe sort of fit semi-snugly inside the filter. I contacted EVOMS, to make sure I was not missing something like a clamp or some such. They did respond quickly and we very nice, but they assured me that is how it was supposed to be. Looking at other installs of this I see the same thing. What I have noticed however is twice in the month or so I have had it, the filter has slipped off the connecting pipe, and caused a cel to be thrown. This is not a big deal to fix, but the design seems a bit off. I also had another issue with it where the pipe attaching to throttle body slipped off while under load on the freeway (waaay unfun), since this happended only once I don't think it has much to do with the cai design.

When this thing is on, and all the parts are connected, i love it, throttle response is great, sound is just awesome. Today I was at my shop and they were also commenting on how it did not seem to fit 'quite right'. We messed with it for a while, and I showed them how it fit in there. They also seemed to think it shoudl have another clamp or a better way to secure the filter. I am wondering if a better coupling of the filter to the throttle body pipe could be achieved with a silicon sleeve or the cutting the pipe and using two seperate silicone hoses , one on each side of the maf, the hose from the fabspeed one seems like a good candidate.

I want to be clear that in no way I am trying to slam EVOMS at all, they have sold tons of these things, and like I said when its on, I love it. I am just wondering if anyone has run into this, or if they have any ideas.

Thanks much

Makulu, My Evoms CAI came with a large jubilee clip that secures the filter to the Throttle Body tube, I couldn't pull that thing off if I tried!

Redbarn, That is something that did not come with mine, would be great if it had. They do not even mention it in their instructions or in any pics of the system. Its nice to know I am not crazy thinking that thing should be attached :)
