✅ Fitment & Function
-
GM-based Indmar engines):
-
2007 & Newer, when the ETX/CAT was introduced
-
5.7L/383/6.0L(L96)/6.2L(LS3)
– Used in both upstream (pre-cat) and downstream (post-cat) positions -
Ford-based Indmar Raptor engines (6.2L):
– Used in downstream (post-cat) only
– For upstream (pre-cat), use a wideband O2 sensor (Indmar #597094)
🔧 Features:
-
4-wire heated narrow-band sensor
-
OEM plug for direct-fit installation
-
Pre-applied anti-seize on threads
-
Helps maintain optimal air-fuel ratio, fuel efficiency, and emissions compliance
⚠️ Important Notes:
-
Check engine fault codes (SPN/FMI) to confirm sensor position (e.g., Bank 1 Sensor 1 = upstream passenger side)
-
For Ford Raptor upstream use, see Indmar part #597094
