AE86 20v Custom Vacuum Line Kit

Chasing a vacuum leak on your 20V swap? If you've ever spent a weekend with a can of carb cleaner hunting down a cracked vacuum line under the ITBs, you know the pain. Old, dry-rotted rubber lines are one of the most common headaches on a 20V 4AGE — and they're hidden in places that make them a nightmare to reach. We built this kit to fix that once and for all. It replaces every single vacuum line on the engine, including the ones tucked under the ITBs, so you can knock out every potential leak point in one shot. Adapted from our popular AW11 kit and dialed in specifically for the AE86 crowd, with fitment for Blacktop, Silvertop, or Silvertop running Blacktop electronics. 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 dial the kit in to how you want your bay to look: - A/C idle-up lines — add them if you're keeping A/C functional - Engine hook delete — skip the hook lines for a cleaner engine bay Every kit is hand-built to order right here in the USA. Fitment: Toyota Corolla AE86 with 20V 4AGE swap (Blacktop, Silvertop, or Silvertop with Blacktop electronics) 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.
