Fitment & Setup Notes

2007.5–2009 vs. 2010–2012: Piping/boot sizes and some intercooler cores differ. Match parts by model year and VIN.
2010–2012 cold-side pipe: OE plastic can split under load. Upgrading to a metal pipe/boot kit with quality clamps is strongly recommended.
Torque T-bolt clamps evenly and re-check after heat cycles. Lightly bead-roll tube ends for added retention at higher boost.

Frequently Asked Questions

Will a larger intercooler increase turbo lag?

Quality bar-and-plate cores with efficient end tanks typically show minimal impact on response while lowering IAT and pressure drop. Correct piping size and leak-free boots preserve spool.

Do I need tuning after installing an intercooler?

No tune required for direct-fit hardware. Tuning can optimize fueling/timing to take advantage of cooler, denser air—especially on trucks with additional mods.

Which clamps should I run?

Use high-quality T-bolt or constant-tension T-bolts sized to your boot O.D. Re-torque after the first few heat cycles and anytime a boot is removed.

How do I fix a blown cold-side pipe on my 2010–2012?

Replace the plastic OE pipe with a metal pipe/boot kit and quality T-bolt clamps. Inspect boots for oil saturation and replace as needed.

Tip: When upgrading pipes, clean the intercooler inlets/outlets and verify MAP/IAT sensor connections and harness slack after reassembly.
