What It Is
A factory-spec replacement intercooler for the Mk4 ALH engine, sized to match the original equipment unit.
Signs You May Need One
A failing intercooler, or a crack in its piping or tubes, commonly shows up as reduced acceleration or a hissing sound under acceleration, sometimes accompanied by a check engine light from the resulting boost leak.
Fitment
1999-2003 Mk4 Golf and Jetta TDI with the ALH engine code.
Common Questions
How do I know if my intercooler needs replacing?
Common signs include a noticeable drop in acceleration or a hissing sound when accelerating, often paired with a check engine light from the boost leak that follows.
Is this a performance upgrade or a stock replacement?
This is a stock, factory-spec replacement, sized to match your original intercooler rather than a performance upgrade.
Does this fit the BEW engine?
No, this specific intercooler is sized for the ALH engine. Check with KermaTDI for the correct part if you have a BEW-engine car.
