Helpful Notes

Fitment window: Many intercooler kits list 1994–2002; your 1998.5–2002 trucks are included—check listing notes.
Pipe sizing: Most 24-valve builds run 3.0" hot/cold-side tubes; 3.5" can help at higher flow if space allows.
Boot & clamp selection: Match boot I.D. to tube O.D.; use constant-tension or T-bolt clamps and re-torque after heat cycles.
Leak testing: After installation, pressure-test to ~20–30 psi and soap-check joints before road tests.

Frequently Asked Questions

Will a 94–02 intercooler kit fit my 1998.5–2002 24-valve?

Yes—most performance kits cover 1994–2002. Verify any small bracket/shroud notes on the product page before ordering.

What size boost tubes should I run?

3.0" works well for towing and street builds. Step to 3.5" only if your turbo/HP goals demand more flow and you have the clearance.

How do I stop boots from blowing off?

Use fresh 5-ply silicone boots, quality constant-tension or T-bolt clamps (see sizes on the 98.5–02 boost tubes page), clean bead-rolled pipe ends, and re-torque after initial heat cycles.
