SPDZ1 Miniature Cat O2 Sensor Check Engine Light Fix 90° – Large Configuration
Eliminate the CEL. Unlock Your Exhaust’s True Sound.
Upgraded your exhaust and now stuck with that pesky check engine light? The SPDZ1 Miniature Cat O2 Sensor CEL Fix (90° Large Configuration) is the solution you’ve been looking for. Designed specifically for high-flow exhaust setups, this sensor adapter is built to simulate proper catalytic function, helping eliminate OBDII codes such as P0420/P0430 – Catalyst System Efficiency Below Threshold.
Each SPDZ1 fouler includes a miniature catalytic converter built inside, offering just enough back pressure and chemical treatment to help fool your rear O2 sensor into thinking everything is running smoothly—without affecting the raw performance of your modified setup.
The large-body version with a 90° angled design provides extra clearance and internal volume, making it ideal for forced induction 6-cylinder builds, V8, and even V12 applications. Still running a 4-cylinder with a high-flow or decat exhaust? No problem—this fouler works there too.
Key Features:
✅ Built-In Miniature Catalyst Element to Reduce CEL Triggering
✅ 90° Angled Design for Tight Spaces and Better Fitment
✅ Perfect for Turbocharged 6-Cylinder, V8, V10, and V12 Engines
✅ Also Effective on High-Performance 4-Cylinder Builds
✅ Eliminates Common CEL Codes Like P0420 & P0430
✅ Durable, CNC-Machined Steel Construction with Heat-Resistant Coating
✅ Simple Screw-In Installation – No Welding, Cutting, or Tuning Required
Whether you're running aftermarket headers, test pipes, high-flow cats, or full decat systems, the SPDZ1 Miniature Cat O2 Sensor Fix helps keep your dashboard clean while letting your exhaust breathe the way it was built to.
