Race German - Smoke Tester BMW Adapter

*Now Upgraded! These smoke tester adapters are now CNC'd from solid delrin.

Our BMW smoke test adapter is made specifically for our BMW Smoke Leak Detector but can be used on other machines. These adapters come in 2.5", 3" or 3.5" to perfectly fit the intake tube of your BMW. Simply remove your airbox and mass air flow sensor, and place the smoke test adapter inside the intake boot. Tighten down with the OEM hose clamp. This will create the perfect seal to leak test your BMW engine. No need to find another vacuum line to tap into.

*If you are unsure of the size you need, make sure you measure your application before ordering.

• 2.5" (Fits M20 Engines & Others)
• 3" (Fits most BMW Engines including M50, M52, S50, S52)
