Didn't know they had these. I remember one member doing some tests on his car by covering the secondary hole and I think it did show some gains.

At $20, it seems like a non-issue but would love to get more feedback from anyone who's done it.

Surprisely, I didn't do it yet. I think at high speed, the air-box already get pressurized enough.

Edit: just revisit ///Marshall report, he lose 10hp peak but gain some in mid range. I guess that what make me hesitate to get the plug. I need every hp at top end.

What are you up to now Kenny??

For $20, if these plates really do provide 5-10rwhp, why WOULDN'T all of us do this??? What caveat am I missing?

But in the second link where Eloy posted the dyno charts, he says peak was the same and even the graphs seem to show the same up top.

I think it just hasn't been advertised and people just overlook. I will double check with Eloy and do pre/post dyno with the plug to see it myself on my next visit (hopefully this sat). If power lose, just remove it then.

P.S. Just need to more cars to do it, so more data can be confirm/evaluate.
