Riffraff Plenum inserts FTW!!!
I don't "beat on" or race my truck, but I do like to tinker, and after taking my intake spider off and on a few times, I was concerned about over-tightening the plenum clamps. Then I found out about the Plenum Inserts from Riffraff. Simple, solid engineering for a problem. I ordered them last Christmas but due to weather, moving, and then not being able to find them, I just put them in last Saturday.
You're not going to get a change like you will with good tunes, but it's nice to not have to worry about going too tight in such an inconvenient spot. Bonus is that I might have had a very slight boost leak there, but with getting everything cleaned up, re-aligned, and put back together tight, I've been getting on her a bit and my mileage has gone up just a hair. I know the lie-o-meter is just that, but the relative changes have proven quite accurate for me.
If you're going to be swapping turbos, up-pipes, or just have 2 hours and less than $100 to spare, you can't go wrong with these inserts. You'll never wonder if you can go just a bit tighter to avoid a leak, and to me, that's money well spent.
Thanks Clay!!

I also just installed mine, yesterday as a matter of fact while doing an HPOP R&R. I re-installed with t-bolt clamps. I agree, these inserts hold up to a good tightening. I did find that the stock plenums were a bit deformed and had to work on them a little to get them back to being round enough to get the inserts installed. I'm sure glad Roland (Mueckster) posted a tip about using a cotter pin puller as an aid to getting the spider back in the boots. It certainly made the job easier.

I purchased a set of the plenum inserts, as well. I talked with Clay, recently, and will be getting the rest of his boots before installing them and my RR. I already had the IC boots for my 6.0 IC install. He is going to fix me up with the rest of them. Thanks Clay.
Robin, I'm glad something I said was useful to someone. lol I've been using a cotter pin puller for hose removal and installation for years. I've even used it to pull cotter pins a few times.

Yeah, well I broke into my own truck one time using just a quarter
Seriously. Some "thugs" broke into my S10 blazer at orientation to college, and used a scredriver to jimmy the lock cylinder. I was a cheap college student, and just put some JB weld around it. After all, there was nothing to steal now that they got my stereo. One night I had locked my keys inside, and wedged a quarter out of my pocket underneath the cylinder and leveraged it out. My buddy was dumbfounded. Only persont to ever break into a vehicle with a 25 cent piece
I also broke into my old jeep cherokee one drunken night using a friends house key, but that's another story.

I had to get a set of the inserts as soon as I saw that Clay had them available. It immediately struck me as a GREAT idea knowing how thin and frigile the stock plenums are. That's why Ford has standard worm gear clamps there and not t-bolt. The set I installed went in like a greased pig (it took a little tapping with a soft headed hammer 
) but the worm gear clamps never saw the truck again and now sports t-bolts on all the boots.
