Up for sale is a set of Weistec High Flow Filter Set for the M157 or M278 engine that is almost new. There is less than 500 miles of usage. $150 shipped to the lower 48 states.

 

Why you selling them ? did they throw any codes when you used them?

 

The reason I am selling them is because I ended up getting the UPD Cold Air Induction kit which comes with it's own filters. No codes were thrown while I had these filters.

Sold!

 

How long have you had the UPD cold air induction kit and what is the HP/TQ gains Jose.

 

Have had the UPD kit for a couple of weeks now. No idea what the gain is since I did a retune at AMS after installing this kit as well as the catted downpipes.

 

Would you say it's a noticeable difference in power when you had the UPD kit installed? What exactly is the UPD kit and what does it do if I may ask. Thanks.

 

The UPD kit is just a spacer that lifts the filter out of the air box to increase volume. I can't say I notice the difference because my car does 620 hp and 750 tq at the wheels, so any increase would be relatively small. What I can say is that peak HP now happens at about 5000 rpm and it is pretty flat until redline.

 

I was reading this: https://mbworld.org/forums/w212-amg/615916-150-hp-peak-200-hp-mid-range-gains-over-stock.html

And thought that was what you got. So this means you got the UPD kit without the performance crank pulley? Same supplier as the attached link?

Thanks.

 

I just got their air intake. Here is the link - http://ultimatepd.com/2011-2015-merc...boost-kit.html

 

Interesting. Thanks for sharing.

 

I have the UDP and made 18RWHP and 26rwtq on the dyno (back to back runs)

 

Any sound difference with the UPD? More turbo noise?

 

i have it too, no noticable noise difference

 

Do you notice a difference?

 

maybe just a little on highway, but kinda hard to tell advertised 20 whp on 600whp car.... Im sure there's benefit but its not big enough that you are gonna feel
