I 've been trying to install a AN Big Sucker A/C on my 08 SERK. I have kit 18-512 for the 2008 Touring models. The instructions say to leave the throttle body support bracket in place so I did. Well the pleats on the top half of the filter are getting compressed when I attach and torque the 3 button screws that attach the filter to the backing studs. I've been in contact with Ness and sent them a pic. The engineer says I got one of the early kits that doesnt have a spacer or some crap. says to put a couple 5/16's washers behind the center screw. I think thats BS and wont work. Has anyone ran across this.

I ended up buying a HD screamin eagle stage 1 kit becuse of this but have not installed either yet. The screamin eagle kit says to remove the support bracket while the Ness unit says to leave it on for their kit. I think the pleats are bending  because the support bracket makes the top 2 backing studs shorter than the bottom but the ness instructions say leave it on. help!

Going to fast......the air hits the pleats and they deform when you break the sound barrier

only thing I could come up with other than compression

It appears that the bottom of the unit is probably farther out than the top, giving a bowed seat. Put a straight edge across the seat area and make sure it is flat.If it's not shim from the back side to make it flat. I'm not real good at typing my thoughts so if you want pm me and leave a # to call and I will try to explain what I mean.

The stand offs on the back plate are shorter that the depth of the AC element. When you tighten the element down it crushes it as shown. Easy fix, remove the element and use small spacers between the stand offs and the backplate. Don't space it out oo much or the element won't seal on the backplate.

No, No, No,, Looks like it dropped on its side....

That would be my suggestion as well.  I don't think the support bracket would contribute to this particular fit issue.

Remove the 3 screws holding the the element to the standoffs and check the clearance between the standoffs and the plate of the filter element.  There should be a small clearance, that's what causes the element to seal against the backing plate when you tighten the screws.  Just make sure the clearance is the same at all the standoffs, and use small washers to "adjust" the clearance.  If you don't like messing with washers, just bend the metal plate at the mounting holes to adjust the clearance (see sketch attached).  Odds are the plate wasn't located perfectly during manufacture of the filter element, and the top screws are pulling the plate over further than the bottom one.
