Christian (<96 Runner> on the forums) shows you how he did the infamous ISR mod for his 3rd Gen 4Runner.
Christian has submitted a supplement for his ISR mod, and here it is.

Parts Required:
1. 2" radiator hose clamp (instead of the stock clamp) $1.79/pair
2. 2" PVC cleanout plug (from Lowes) $.67

Before painting:
Drill two holes using a 9/32 bit into the square portion of the end cap (as shown).
Screw in the barbed hose fittings (test fit). Using a deep socket will make this much easier.
Remove the hose fittings.
Paint the cleanout plug if necessary.

After painting:
Install the barbed hose fittings.
Install the hose clamp on the intake track.
Install the new intake plug.
Tighten the hose clamp.
Install the PS vacuum line and FPR vacuum line.
Pull the EFI fuse for 15 minutes, reinstall and drive!

If you choose to do this mod good luck, and if you have any questions  (<96 Runner>) on the Yotatech Forum.
