Was driving last night and noticed the car was not performing well and wasn't getting much boost. This morning I decided to check under the hood and the flexible tubing was completely sucked into the air box. I put BMC filters in last month and noticed there was a small tear in the cloth flexible tubing .
Are you tuned? The reason I ask is maybe the additional boost caused more suction on that intake piece. It makes me think back to when I had my old '09 CTS-V. It was a known issue that if you changed the pulleys and increased boost, the OEM rubber intake would collapse under the additional boost so you needed to replace that piece with hard plastic or metal.

yes I have EC tune, I would think a solid pipe would be better too, there is a carbon fiber kit but costs an arm and a leg
When I had my car at AMS, they told me these tubes can collapse when the engine is at higher rpm's with full boost. They had witnessed this several times in their dyno room.

I had them replaced under warranty so yes. I'd love to have an alternative but a crazy expensive carbon fiber intake system isn't exactly what I'd prefer.
Did mine last night. Decided to keep all the OEM couplers (for now). Had the hardest time getting the glue and felt residue off. (Engine bay is a little dusty... blame dusty-*** Texas.)
The existing OEM hoses didn't appear damaged (just dusty) but after I took them off the engine I could tell they were getting brittle and more porous. It wasn't surprising as she's 10 years old now and they've probably never been replaced.
When the job was done (took less then an hour for the entire thing), I took her out for a spin and could immediately feel a difference in throttle responsiveness. It feels like the engine definitely favors non-porous inlets. I only took the car a mile or two down a stretch of country roads near my neighborhood. I didn't expect this mod to make such a difference, but the car felt like it was pushing to be driven harder (like a frisky horse chomping at the bit). It hasn't felt like this in months. I'd been concerned about why the car had been feeling more and more sluggish.Now I know why. So glad I did this little mod. Cheers to Juice1979 and BlownS4 (https://mbworld.org/forums/e-class-w...ml#post7051430) for the pics.
It was easy to do (if a little frustrating to get the adhesive off the OEM parts). Everything was done for a fraction of the OEM price ($21.99 each kit at O'Reilly Auto Parts), and I saved on an hour's worth of labor by just doing it myself. Thanks for the advice. This mod works. And no more worrying about the dreaded factory hose flying apart into my engine!
(Also, Spectre Performance is apparently owned by K&N - found that out yesterday- so the products feel pretty solid - and seem to be getting more and more popular.)
