Key Features of Ford 3.5 EcoBoost Engine

The Ford 3.5 EcoBoost engine comes with some excellent features that make the engine more efficient than others with similar specs.

Here are some of the key features of the Ford 3.5 EcoBoost engine:

1. PFDI Fuel Injection System

The engine uses a Port Fuel Direct Injection (PFDI) system, which is a combination of port fuel injection and direct fuel injection. It optimizes fuel delivery and combustion for improved performance and efficiency.

2. Twin Inter-Cooled Turbochargers

The engine is also packed with twin inter-cooled turbochargers that are mostly found in high-performance engines. The inter-cooling system helps cool down the compressed air in the turbochargers. In turn, it improves combustion efficiency and power output.

3. Variable Camshaft Timing

The Ford 3.5 EcoBoost engine uses a Variable Camshaft Timing or VCT system. It guarantees exact timing for the intake and exhaust valves of the engine. The process plays a crucial role in improving the engine’s fuel efficiency.

4. Integrated Exhaust Manifold

The Ford 3.5 EcoBoost’s integrated exhaust manifold design combines the exhaust manifolds with the cylinder heads. It improves the turbo response and reduces turbo lag for better engine performance.

5. Other Notable Features

Apart from these key features, there are a few more features in the Ford 3.5 EcoBoost engine that are worth mentioning:

  • Engine Control Module (ECM) to optimize fuel efficiency and improve engine performance.
  • Dual Overhead Camshafts (DOHC) for better power delivery.
  • High-pressure fuel system for efficient combustion.

Ford 3.5 EcoBoost vs 3.5 PowerBoost Full Hybrid: Performance Overview

To better understand its capability, let us contrast the 3.5 EcoBoost engine in the Ford F150 with its PowerBoost and High Output variants:

SpecsHigh-output 3.5L EcoBoost3.5L EcoBoost3.5L PowerBoost
Power450 HP400 HP430 HP

Towing capacity8,200 lbs.14,000 lbs.12,700 lbs.
Payload capacity1,410 lbs.3,250 lbs.2,120 lbs.

Compared to the other two versions, the 3.5L EcoBoost engine offers balanced performance with superior towing and payload capacity.

Ford 3.5L EcoBoost Engine: Problems & Reliability

Like every other engine, the 3.5 EcoBoost engine is also not free from problems. Multiple users have reported the following problems with their Ford 3.5 EcoBoost engine:

  • Spark plugs and ignition coils have low durability: The spark plugs and ignition coil often damages earlier in Ford vehicles with 3.5 EcoBoost engines. It usually happens due to the extra pressure from the engine.
  • Timing chain problems: The vehicles also have timing chain issues that cause rattling or ticking noises. It can lead to serious damage to the engine.
  • Carbon build-up: Carbon build-up is a common issue for engines with direct fuel engines and is no different for the Ford 3.5 EcoBoost. The good thing is regular cleaning and maintenance keep this problem away.
  • Oil breaks down: Some users also reported oil breakdown issues in their vehicles with Ford 3.5 EcoBoost engines. It usually happens due to rough driving or putting too much pressure on the engine.

These issues are minor, and most are fixed in the second generation of the Ford 3.5L EcoBoost engine. Hence, the engine is completely reliable for balanced performance.

Ford 3.5 EcoBoost Engine Modifications

The Ford 3.5L EcoBoost engine already offers a smooth and satisfactory performance. But you can still modify some parts of the engine to get better performance.

I recommend the following modifications for the Ford 3.5 EcoBoost engine:

  • Blow-off valves: Upgrading the blow-off valve can improve the throttle response and also prevents damage to the turbocharger.
  • Downpipes: It is a part of the vehicle’s exhaust system, and changing it will improve the gas flow to make the turbochargers more efficient.
  • Intercooler: Upgrading the intercooler will result in better airflow and more effective cooling of the compressed air.
  • Intake: It increases the airflow for better combustion and improves power efficiency.
  • Suspension: Upgrading the suspension allows the rider to handle the vehicle better and offers more comfort.
  • Tune: A tune upgrade or modifying the electronic control unit (ECU) can improve the overall performance, including better acceleration, improved throttle response, and more.

My Opinion: Is the Ford 3.5 EcoBoost a Good Engine?

In my opinion, the Ford 3.5 EcoBoost is a pretty good engine in terms of performance. You will get performance similar to V8 engines, but it saves more fuel.

Suppose you cannot afford high-end engines but want efficient performance, good fuel economy, and superb towing and payload capacity. In that case, the Ford 3.5L EcoBoost engine can be a perfect choice.
