Cold Air Intake that was on our 300D Turbo when we bought it. I liked the performance it gave us and the little extra fuel economy since we are restoring ours to stock we will not be using it. The receipt showed the previous owner paid $359 for it. I am in Dallas.

$250 obo

Thanks

Would you like to expound on your theory? I have run them on my dodge ram mechanical injected 12V that I drag race, my jetta TDI, my VW Caddy. Everyone I race with runs them on their diesels .

Banks, BD Diesel, Extreme Diesel, Bullydog and other diesel performance companies sell them for their performance kits.


So my question is, are you saying for Mercedes Diesels they are no good? If so why?

Now there is a true statement, it has an isolation canister or flange.
Can you show it?

There is NO power increase with that filter. Only an increase in noise, reduction in turbo lag and reduction in filtering efficiency. The stock air filter is a true cold-air intake and can flow about 450cfm, almost 40% more than the engine uses.

$150 is far too much. Nobody should pay more than $0 for a warm-air intake kit. If the PO paid $359 for that then he got scammed big time.
