Advance Headers High-Performance Stainless Steel Exhaust Extractors for JEEP 4.0L EFI Inline 6
The Advance Headers Premium Stainless Steel Performance Exhaust Extractors (A145SS) are precision-engineered for the legendary 4.0-Litre Inline 6-Cylinder EFI petrol engine found across the Jeep Cherokee, Grand Cherokee, and Wrangler platforms (1994–Onwards). Upgraded to a premium high-grade stainless steel construction, this heavy-duty tubular manifold replacement addresses the notorious cracking issues found in original factory setups while delivering maximum exhaust scavenging velocity and enhanced low-end off-road torque.

⚠️ Crucial Wrangler Installation Fitment Note:
When installing this extractor set on Jeep Wrangler (TJ models), please be advised that minor custom positioning work is required. Due to chassis and transmission configuration variances on Wrangler models, it is necessary to slightly reposition the downstream exhaust system piping layout where it wraps around the gearbox bellhousing area to guarantee safe operational clearances.
Please Note: Due to the intensive configuration modifications required on the intake/exhaust face of the Jeep inline block, this component has an estimated fitting time of 5 hours. Professional installation by a qualified 4WD mechanic or exhaust specialist is highly recommended to ensure perfect sealing and custom alignment.
