AW11 16v 4age Custom Vacuum Line Kit

Hunting a vacuum leak on your AW11? This is the fix. The 16V 4AGE in the first-gen MR2 is a great little engine — but four decades of heat cycles take their toll, and cracked, dry-rotted vacuum lines are one of the most common reasons these cars run rough, idle weird, or throw mystery issues that'll have you chasing your tail with a can of carb cleaner all weekend. This kit puts an end to that. It replaces every vacuum line on the engine, including the ones tucked under the intake, so you can knock out every potential leak point in a single shot. Dialed in for the AW11 with specific fitment for 85/86 and 87+ cars. Every line is made from professional-grade high-temp silicone — way more durable than factory rubber and resistant to the heat cycling that kills stock lines. Each line is pre-cut to the correct length, bagged, and labeled, and we include detailed instructions so there's no guesswork during install. You can also tailor the kit to your car: - Add A/C idle-up lines if you're keeping A/C functional - Add cruise control lines if you want to refresh the cruise vacuum module setup Every kit is hand-built to order right here in the USA. Fitment: 1985-1989 Toyota MR2 AW11 with 16V 4AGE (85/86 or 87+ specific variants available at checkout) Important: These lines are press-fit silicone, just like factory rubber — no clamps required on a naturally aspirated engine. If you're running forced induction (turbo or supercharged), you'll need to add clamps on the pressurized lines to keep them seated under boost.
