I don't think I would buy it for the "claimed" horsepower increase but I would be interested in it for the cold air induction. That alone will give a hp increase. I haven't see anything like that here in the states but if and when I do I would be interested in them.

I wouldn't

I'm not sure about the E320, but my E420 already had cold air induction. It takes air from a scoop in the front of the car and routes it through the negine space, through the filter, and into the engine.

Another thing you'll need to worry about is filtration efficiency. If you're getting the claimed HP increase because the filter is less constricting, then it will also be letting more grit into the engine. That's not good. I'd stick with MB filters and design. If it were that easy to SAFELY get more horsepower out of an engine, I think MB would have already designed in such a system.

Snake oil

Do you really think Mercedes would have gone through all the trouble to offer a 320 engine for the SLK, which gives 22 more horsepower over the 230 kompressor engine, if all they had to do was install this intake?

Notice the hype but no figures on the product's CFM improvements?

The important thing MB wanted to achieve by getting a V6 in the SLK is:

1. A Better exhaust sound
2. Much more torque than the 2.3K

A filter could not offer neither of them...

Also, MB could have produce a Pulley kit and the 2.3K will offer more hp than the 320 engine... (Pulley kit like Kleeman, Carlsson,etc offer) You probably get my point

5 to 20HP? Sure.
If you combine this to the recently advertized Tornado gizmo, a few bottle of ProLong additive, 6 Tritanium Super spark Plugs, a couple of bottle of octane boster into Premium gasoline and a chromed exhaust pipe, that would turn my 260E into an E55 beater.
I'll have 2 please.
Keep your money for a few good books on performance improvements.

All current production cars I know of have cold air intakes, no one pre-heats anymore, since they don't have carbs to freeze up.

5-20 hp is only going to be available a WOT, and I almost never drive that way -- can't affort to blow an engine just for fun, I work for a living.

Hp increases from fancy intakes usually have more to do with less flow restriction through the filter housing, and concommitant higher noise levels, not better flow through the filter.

Do as you please, I'm prefectly statisifed with the stock filters.

And PLEASE, this isn't 1950 when Detroit would stick a 1 barrel carb on a flathead V8, ALL intake systems are engineered, not scribbled on the back of an envelope after a long drinking session at the strip club...... Quiteness of operation, engine longenvity (people DO expect the engine to outlast the second lease payment, after all...) and ease of service are all part of the equation, along with horsepower output, cam timing, exhaust backpressure, milage requirements, etc. It ain't just a matter of "lettin 'er breathe more".

All oiled foam aftermarket filters allow more dirt through than OEM (NOT cheapo aftermarket filters!) paper filters, and all will trash a flow sensor if the oil gets down into intake, as it will if you oil it enough to actually trap all the dirt. OK the first time, but the second "two months without beer because the $600 MAS got trashed" isn't that much fun anymore.

These are NOT the same as a real oil bath filter, which is MUCH more efficient at removing dirt. Not at allowing air flow, but he really do remove dirt. They also oil the intake nicely, no one has used them since the early 70s, and I think Benz was the last holdout.
