The Volvo D13 engine is known for its reliability and fuel efficiency, but like any commercial engine, it requires regular maintenance and occasional repairs. One of the biggest questions for fleet owners and independent truckers is whether to opt for OEM (Original Equipment Manufacturer) parts or go with aftermarket and wallet-friendly alternatives. Below, we break down the pros and cons of each approach for different components, helping you make informed decisions based on cost, longevity, and overall performance.
Here’s Why Volvo’s Are Good Semi Trucks!
Common Repairs and Fixes: OEM vs. Wallet-Friendly Alternatives
- OEM: Genuine Volvo injectors are built to factory specifications, ensuring proper fuel atomization and longevity. Expect to pay $400–$600 per injector, depending on the supplier and whether installation is included.
- Wallet-Friendly: Aftermarket injectors range from $250 to $400, but their quality can vary. Some high-quality aftermarket options provide decent performance, but lower-end options may lead to premature failure, rough idling, or fuel efficiency issues.

- OEM: Volvo’s EGR (Exhaust Gas Recirculation) components are designed for optimal engine compatibility but come at a high price—$1,500+ for a new EGR cooler.
- Wallet-Friendly: Aftermarket EGR coolers cost $500–$900, though their performance varies. Some truckers opt for EGR delete kits (where legal) to bypass this system altogether, costing $400–$700, but this requires custom tuning to avoid engine warnings.

C. Turbocharger
- OEM: A factory Volvo/Mack turbocharger can set you back $3,000+ but guarantees reliability and efficiency.
- Wallet-Friendly: Aftermarket and remanufactured turbos range from $1,200 to $2,500. While some well-known aftermarket brands deliver solid performance, poorly built turbos can lead to power loss, excessive boost lag, or premature failure.

D. DPF (Diesel Particulate Filter) & DEF System
- OEM: The DPF (Diesel Particulate Filter) is a critical emissions component, with a factory replacement costing $3,500–$6,000.
- Wallet-Friendly: Aftermarket DPF filters can be found for $1,500–$3,500, but be cautious—low-quality options may clog faster, leading to frequent regenerations and expensive downtime.
Volvo D13 Install and Replace DOC/DPF (2008-2018)
- OEM: A complete Volvo/Mack overhaul kit (including liners, pistons, bearings, and gaskets) typically costs $12,000–$18,000.
- Wallet-Friendly: Aftermarket kits from trusted brands like IPD, Mahle, or PAI can cost between $6,000 and $12,000. While some provide comparable performance, subpar kits may have weaker gaskets and bearings, leading to early failures.

When to Splurge vs. When to Save
Not every component requires an expensive OEM replacement. Here’s a quick guide on when to stick with factory parts and when an aftermarket alternative can be a smart money-saving option.
OEM Recommended for:
- Crucial engine components (fuel injectors, ECM, turbochargers)
- Emissions parts (DPF, DEF systems, EGR valves & coolers)
- Electrical components (wiring harnesses, sensors, engine control units)
Wallet-Friendly Works for:
- Routine maintenance parts (filters, hoses, belts, coolant tanks)
- Some performance upgrades (turbo rebuilds, high-flow exhausts, custom tuning)
- Non-critical parts (exterior accessories, cabin components)
