Due to the low, wide mount, the boxer engine can prove difficult to service. Even changing spark plugs can be a substantial job. However, boxer engines are known for their reliability, and should require less service than most other engine types.
What are the advantages of a boxer engine?
The advantage of a boxer engine is that the engine counter balances itself. The pistons that are across from each other move toward the crank and away from the crank at the same time. This gives smoother operation and a crank shaft that is lighter because no counter balance weights are required.
Why are boxer engines bad?
The disadvantages of the boxer engine include the engine size and the difficulty of maintenance. Other manufacturers have meddled with the boxer engine, but Subaru and Porsche are the only manufacturers that still persist with this engine configuration until today.
Is Boxer engine better than inline?
Inline engines feature pistons that sit upright and move straight up and down. This means the engine block is taller overall and has a higher center of gravity than a SUBARU BOXER® engine, which features pistons laid flat. The upright layout of inline engines means they can vibrate more during operation.
Are boxer engines more powerful?
Boxer engines derive several performance advantages inherent to their design, since the center of gravity on an opposed engine is much lower to the ground compared to an in-line or V design. … Lower profile also makes power transmission more even, as the engine is on a plane closer to the rest of the drive-train.
What are the disadvantages of a boxer engine?
The downside of a boxer engine from a balance perspective is that pistons don’t sit directly across from one another, meaning they can create a torque that tends to want to rotate the engine about the vertical axis.
Is the Subaru boxer engine a Porsche?
Subaru is the only automaker on the planet that uses the boxer engine in its entire lineup. They use it in the Forester, Outback, Crosstrek, Impreza, WRX/STI, Legacy and BRZ. Porsche is the only other automaker that uses the flat, H-shaped, opposed-piston “boxer” engine. … Subaru says that won’t change in the future.
Do Subaru engines last long?
While results will vary and the big variable is always how well the car has been maintained, what I can tell you is a Subaru is capable of going 300,000 miles. And if you are a regular maintenance type of owner you should expect to get that type of mileage out of it.
Are Subaru boxer engines noisy?
A 2.5-liter “boxer” flat-4 engine is heading your way, and it’s eager to spit noise into your ear holes. … The 2.5-liter Subaru engine makes use of something called unequal length headers, which are exactly what they sound like.31 мая 2016 г.
Why do Subaru engines fail?
The Subaru engine defect is reportedly caused by a subpar connecting rod and bearings that begin to disintegrate and shed metal into the engine. As the oil becomes contaminated, the engine begins to suffer, with owners reporting knocking and shuddering.
What type of engine is the best?

Is V engine better than inline?
Inline or parallel engines have pistons placed literally in parallel positions to each other. … A V engine also produces more torque at lower rpms because of the power stroke coming from two sides of the crankshaft. An inline engine is more balanced than its V counterpart because of the equal weight distribution.
Why do boxer engines burn oil?
Boxer engines can burn more oil. Oil more easily pools in the cylinder heads and can leak into the cylinder. Likewise, oil finds its way to the bottom of the cylinder and stays there longer vs gravity taking it down past the rings.
Why are Subaru engines so noisy?
The release of the high-pressure combustion gasses entering the exhaust system causes this noise. Depending on several different inputs into the ECU, such as engine coolant temperature and throttle opening angle, this noise could occur until the engine coolant temperature reaches the desired temperature.
Which Subaru engines to avoid?
Subaru 2.5-L Turbo Four Cylinder
Owners of 2009-14 Subaru Impreza WRX and WRX STI models have launched a class-action lawsuit, alleging the pistons and PCV (positive crankcase ventilation) systems in the high-performance 2.5-L turbocharged engines may overheat or malfunction, requiring a king’s ransom in repairs.
