The full rundownProduct details
One plug, a dozen uses. This DL 090 Sealed Series 4-pin connector is the factory replacement for several critical sensors across the Subaru and Mazda lineups. Whether you are repairing a heat-damaged Ignition Coil plug on your WRX or refreshing the TPS/Crank sensor on an RX7 or MX-5, this kit provides a secure, weatherproof connection that exceeds OEM standards.
Because these connectors are often located near the exhaust manifold or cylinder head, the plastic clips are prone to snapping. This kit allows you to replace the housing and terminals, ensuring your engine vitals stay connected even under extreme vibration and heat.
