I am looking at a set of used Renntech airboxes and ECU's. Does anyone have any opinion on weather their is a noticeable difference in performance with these upgrades. Even used they are still expensive.

Sean, aka djblu recently installed these M119 RENNtech items on his 95 SL500.

Please take a look at page 11-12 from M119 Performance Modifications .

Opinions in regards to the RENNtech M120 airbox upgrade, as well as other options can be found at Performance Modifications for SL600 .

I know, that pricing is ridiculous. Trust me, I'm not suggesting going with a tuners solution. But I would suggest a custom intake that would allow your V12's to breath easier.

I'd be willing to assist in finding an affordable solution, but I'd need someone to give me the inside dimensions of the entire intake in order to do the proper research on replacement parts.

I've posted a few pictures comparing a modified air box to a stocker to show you all an example of what I mean.

I've considered it but couldn't do it

The airbox and ECU flash isn't that bad of a price... but still $1500 is a lot of money and you only get like 10 horsepower.

The M113 supercharger they offer gives really nice horsepower, but I threw up in my mouth when I saw they wanted $15,000 for it :eek:

Mr_Clifton I bet Alex (Tech-Tune) spent probably 1 third of that price.

Cheers.

Kleemann offers a supercharger system for the M113 for $6999.
Its definately a better value over the RENNtech system and will net the same results.
