I just looked this am and have not noticed any warpage but it has only been about 2 weeks now. But I would like to be prepared if it does start.
Thnx.

If you go up a few posts you'll see a link that he posted for a fix.

I think I had warpage because of the overtightening.
That and I have a 150 mile round trip drive to see my girlfriend that I make 1-2 times a week.

Use properly sized hose clamps from the auto store on all ISR plugs. I apologize if this has caused anyone inconvenience. I feel bad.
The stock clamps just were not designed to apply even pressure on slightly smaller diameter PVC plugs. It simply distorts them over time.
I am here to assist if anyone has any questions.

Well, I have to say I appreciate you bringing this minor thing to our attention as soon as you did.
I'm surprised at how little time it took for mine to warp! I probably wouldn't have noticed until I did something seriously bad to my engine.
Out of curiosity though - with the plug being warped would that have affected my mileage? I was noticing poorer than usual mileage until last week. I figured it might have been my driving (maybe more aggressive than usual).
Anyhow thanks again for the heads up!
Trust me - your ISR cap is much better than the version I had before (muy ghetto).

Rubber grommet that fit into a plastic cap. The cap went OVER the intake lip (literally a cap).
The 3/4 OD fuel line was a snug fit into the grommet and I used (at first) non-sensor safe silicone sealant. I think I emptied out like 1/2 a tube
After my check engine light I pulled the EFI and coated everything with sensor safe stuff.
I think you did a professional looking job with ghetto parts.

I really don't understand how it could shrink... all I can offer is maybe just using a real light coat of some kind of tacky grease or something.
I really couldn't tell you though.

Are you trying to put it back on with a hose clamp in place?
Many times the hose clamp needs to be loosened nearly all the way.
Another way of asking this question: Will the original silencer box fit without a hose clamp in place?
