Thumbs up ISR Mod 96 - 98's: Permanent fix found (with pics)

Most of you will recall this thread (now a sticky) about the ISR mod warping on 96 - 98 3.4's.

I finally found a permanent fix, and it looks better too!

There are two new parts:

1. 2" PVC cleanout plug (Lowes $.66)
2. 2" Hose clamp (any auto store)

Here is what the plug looks like (sorry it is upside down)


This is the inside (the side that will be exposed to the intake air)


With the barbed fittings in place...


After painting...


The end result:


It fits perfect!

I will get this supplemented to my 96 - 98 write-up.

No, you do not have to use JB Weld. If you drill the hole perfecly, there is no way air can "escape" or be sucked-in. JB Weld was just a safe gaurd.

I can always make one for you Rob, just let me know!

Post Drill bit size

Rob and others-

The drill bit size is 9/32. A deep socket will take care of the barbed fittings. No JB needed!

yea pulled my isr out today, you're right, it's warped as you can see here:



And these babies gave me extra 15 hp while I worked on the rig today



I tried to put my original intake silencer back on, but couldn't get it to fit in the hole, it's like the hole shrunk. Got kind of frustrated, so I just put the isr back in again.

I'll probably try to make a new one sometime this weekend or so.

christian where would I get the barbed fittings?

Cool gloves Rob!

Just put your stock box back in for the time being.

Check out my write-up, Corey has added a supplement to it.

You can get the fittings at Home Depot (probably Lowes too)

I stayed with the plumbing end cap there. The fit is much tighter, and I found no warpage. Wouldnt hurt to go with a new 2" hose clamp there too though.
