Clears P0420–P0434 Without Replacing the Cat | M18×1.5 Stainless Steel O2 Sensor Spacer with Built-In Catalytic Filter | Downstream Only

• ✅ Clears P0420–P0434 — Without replacing the catalytic converter
• ✅ Built-In Sintered Catalytic Filter — Pre-treats exhaust gases before reaching sensor tip
• ✅ 304 Stainless Steel — Heat-resistant, corrosion-resistant, 58mm length
• ✅ M18×1.5 Standard Thread — Fits most downstream O2 sensor bungs
• ⚠️ Downstream Sensor ONLY — Post-catalytic converter position only

Your Check Engine Light Is Lying to You — Here's the Fix

When P0420–P0434 codes appear, most workshops recommend a $300–1,500 catalytic converter replacement. In most cases, the real problem is simpler: the downstream O2 sensor is reading exhaust gases that are too concentrated. This spacer repositions the sensor 58mm further from direct exhaust flow and filters gases through a built-in catalytic mesh — clearing the fault code permanently.

How It Works

1. Spacer threads into existing M18×1.5 O2 sensor bung
2. O2 sensor threads into top of spacer — now 58mm further from exhaust stream
3. Built-in sintered filter pre-treats gases reaching sensor tip
4. ECU reads stable signal — fault code clears
