• Fitment issues caused by non-OE replacement parts

Installation Notes and Tips

Verify core dimensions, inlet and outlet tube size, and mounting layout against the original unit before installation. Confirm hose routing and clamp condition during replacement, especially on Mitsubishi and Isuzu applications where OE-style fitment is important. Inspect adjacent charge-air plumbing for wear, oil residue, or damage that could affect sealing after the intercooler is installed.
