Anyone here have any experience with the Steeda Delete Plugs? I know one guy asked some time back, but no one really spoke up.

While probably only good for 5 rwhp, they still score high on the hp-to-$ area, costing only $59 - $69 (assuming you can get the tune for free from the seller, e.g. Bredspeed, Tillman). Supposedly, with a tune, you don't have the low end torque loss but get the high end hp gain.

I canceled my order today for these. I got scared off by two things:

1. Some internet postings that Steeda fails to include plugs for the holes in which the rods/shafts (which control the butterflies) get removed. Apparently, folks were forced to use a tap and insert a bolt or goop RTV sealant in these two holes. I wouldn't think either solution is conducive to returning the car to stock easily.

2. And, most important, that I would have to take the 1-2 hours to put it back to stock each time in order to have warranty work done. After all, you can't put the original tune back in the car without removing these delete plugs. What would happen if I was traveling and had problems -- I very well might not be in a position to do this before the car hits the dealership for repair.

I'm still tempted, though, as its supposed to create a much smoother power curve . . . completely eliminating the infamous 3000 RPM flat spot where the plates would normally open.

Any experience/thoughts?

I don't understand what these do

I installed them without an issue. I didnt even really need the instructions it was so easy.

There are butterfly plates that open at 3000 RPM to let more air into the head. Obviously, the computer adjusts air/fuel, timing, etc. at the same time. The idea with them is to supply backpressure and torque at lower RPMs with hp at higher RPMs.

With this kit, you remove the butterflies, essentially leaving the air channel open all the time. The "delete plugs" simply plug up the holes that the butterflies left behind.

Yea, I was wondering how it went for you.

How did you deal with the holes left behind by the long rod (that used to turn the butterflies)?

Thats what the steeda plug kit takes care of.

cidsamuth

The plug kit takes care of the holes where the butterflies go. However, the rod goes through those same holes AND the intake manifold itself. If you follow Steeda's directions, the manifold is left with one hole on either bank where that rods originally were.

Look at below post. Maybe I'm missing something:

Branman - you should change that sig. I was scrolling through this post and stopped cold..."what the heck was I doing again" for like 7 seconds.

Nah...dont change it. EVER. Post more often too please.

If you worry about warranty, leave it stock.
