A reconditioned M113 typically costs £2,500–£4,000 supply only [ESTIMATED], with variation by AMG or non-AMG spec. Fitting adds £650–£1,300 depending on the model and labour rates.

Is the M113 a reliable engine?

Yes — the M113 rates 4.5★ out of 5 based on specialist feedback and UK owner data [MB-INTERVIEW]. Its main age-related issues are oil leaks and ignition wear, not internal failures.

Which Mercedes models use the M113?

The M113 powers a wide range: C43/C55 AMG, E55 AMG, S430/S500/S55, SL500/SL55, CL500/CL55, ML430/ML500/ML55, G500/G55, CLK430/CLK55, and R500 — across late‑1990s to early‑2010s models.

How long does the M113 last?

With regular oil changes and proactive gasket maintenance, the M113 routinely exceeds 200,000 miles. Many specialists report seeing examples at 250,000+ without internal rebuilds [MB-INTERVIEW].
