In the winter when cold, I can tell mine are getting weak. Now that the warmer weather is here, they work just fine. I guess that will be on my list one day as well. Thanks for the part numbers. James

I installed a "stealth" CAI on my '04 Coupe LTD. I started with the throttle body upgrade from Needswings, and a meticulous cleaning of the MAF and elbow . Then I installed the larger flow Mercedes M112 airbox found on MBZ CLK 320 / C320 (A1120900701) with new filters. I removed the small restrictive oblong ends of the air intake hoses and replaced that portion with 3" silicone hose. I am showing pics of the bigger airbox, and one with the smaller Crossfire OEM filter on top of the filter box to show how much larger the filters are in the bigger box (sorry - had already installed the new ones and didn't feel like taking them out for comparison.) Even though the 3" hose had to be routed through the oblong openings on either side of the radiator, they still capture a larger volume of air, and I was able to extend them in front of the radiator to capture cooler air (also pictured).
Overall, I have noticed an improvement in mid-range RPM performance - especially in gears 3-5. I think the exhaust sounds much better too. I was able to source the MBZ parts used on eBay, the filters from FCP Euro, and the hoses from Amazon. Overall, I paid less than $150 for the entire project. I like the fact that it has retained much of the OEM look under the hood.

I also installed the Needswings Oil Catch Can while I was at it, and saved a lot of time vs. a separate installation,

I considered an ECU tune, but I am very happy with the performance that I have gained now, and am reluctant to spend the additional money at this point.
The larger airbox fits nicely and beefs-up the overall appearance in the engine bay. One wonders why they went with the smaller OEM air intake set-up in the first place.

OEM filter on top of the larger air filter chamber.  The difference is dramatic.  I had already installed the new filter and didnt want to take it out for comparison, but you get the idea.

Probably the most glaring difference is the size of the OEM oblong shaped intake hose end piece (left) vs. the 3" silicone hose. The OEM parts restrict a lot of air before it even gets to the filters. The hose has to be squeezed to get it through the exit openings on either side of the radiator, but still allows for greater flow and can be extended further in front of the engine and radiator for cooler air.
Oil catch can is easily installed at the same time and saves a lot of time and effort.

Very cool! Thanks for posting.
