Specifications

The AK-23512897 exhaust manifold by Akmi Corp is engineered as a high-quality direct replacement for Detroit Diesel Series 60 engines (11.1 L, 12.7 L, 14.0 L). Featuring a medium-angle turbo mount configuration, this robust assembly includes three sections—front (23511221), center (23514898), and rear (23511222)—for a full installation solution. Constructed to meet or exceed OEM standards, it prevents exhaust leaks, withstands high heat, and preserves engine efficiency. Ideal for heavy-duty trucks, this manifold reduces downtime with easy fitment while offering reliable performance and a one‑year warranty. Sold by Wofford Truck Parts, it’s a cost-effective choice for fleet maintenance and rebuilds.
