You notice any difference after blanks install? Some say theres a loss of tourqe but idk

I have not done it yet. Just waiting for a good day with time. We can't seem to get enough time between weather days and work days.

0 difference. If flaps become available separately for cheap - I'm looking at you, China! - I'll probably install them back, but not because there's any difference in performance.

No code, unless for whatever reason you remove the actuator as well.

Only 1-2 of mine look as bad as yours did. I'm at about 126k on my 2009.


Did you notice a loss of acceleration without them?


(Now I see you answered that.)

Interesting. Also odd that only #3 and #6 are leaking noticeably on mine.

I did a cheap delete since they were a bit leaky due to loose shaft. I read about it on a forum from Europe. I didn't want to have to remove the manifold again , which I would have to do if I ordered blanks.

Remove flaps.
Cut across the plastic and shaft near the rotating sleeve on the side that goes inward to be able to pull out the shaft from that hole.
Replace the hole by threading a screw from the out side into the hole left using thread locker or some strong epoxy.

No change in power, response or idle.
