What It Is
A complete vacuum line kit for the ALH engine, covering everything needed to refresh your car's vacuum system in one order.
What's Included
Why Refresh Your Vacuum Lines
Vacuum lines harden and crack with age, and a compromised line can cause vacuum leaks that affect turbo boost control and overall engine performance. Replacing the full set at once, rather than patching individual sections, helps ensure the whole system is sealed and functioning as intended.
Fitment
2002-2003 Mk4 Golf, Jetta, Jetta Wagon, and New Beetle TDI with the ALH engine code.
Common Questions
Why replace all my vacuum lines instead of just the cracked one?
Vacuum lines age and harden together, so if one has failed, others are often close behind. Replacing the full set at once helps avoid repeat leaks down the road.
How much hose is included?
3 meters of 3mm hose and 2 meters of 5mm hose, enough to refresh the ALH vacuum system.
Does a bad vacuum line actually affect performance?
Yes. A vacuum leak can disrupt boost control and turbo response, so a sound vacuum system matters for how the engine actually performs.
Does this fit my BEW engine?
This specific kit is sized for the ALH engine. Check with KermaTDI for the correct sizing if you have a BEW or other engine code.
