What Is A Splash Shield? Why Is It Important?

Dirt, debris, and moisture are an engine's worst enemies. The space underneath the engine is wide open. When dirt, debris, and moisture enter the engine compartment, they wreak havoc on the engine. That's why splash shields exist.

What Is A Splash Shield?

Subaru Splash Shield On Car

To protect your engine from impurities, Subaru put a splash shield underneath the engine. A splash shield is a flat plastic panel that's bolted to the chassis. Splash shields come in various shapes. Your splash shield could be a unique and elaborate shape, or it could be a simple square. It depends on which Subaru model you have.

What Does A Splash Shield Do?

The splash shield covers the open area underneath the engine. It shields the engine from:

  • Water
  • Dirt
  • Debris

A splash shield protects a lot of engine parts from rust and contamination, including:

  • Alternator
  • A/C compressor
  • Rack and pinion steering system

Do You Ever Need To Replace Your Splash Shield?

Ideally, a splash shield should last forever. However, a splash shield can break any day because it serves as the first line of defense against:

  • Ice
  • Curbs
  • Potholes
  • Speed bumps
  • More

When it breaks, it's wise to replace the splash shield as soon as possible. If your splash shield is broken or has holes, it can no longer protect the engine.

Why Quality Matters

The splash shield may look like a simple part, but it offers a lot of protection. That's why it's important to take quality into consideration when looking for a replacement splash shield.

The likelihood of impurities reentering your engine compartment is higher with a low quality splash shield. If something hits it hard enough, it’ll break and let dirt, debris, and water into the engine bay. You will have no way of knowing until you either:

  • Look under your Subaru and check the splash shield (but how often do you do that?)
  • Notice the symptoms of affected parts

OEM Vs. Aftermarket Splash Shields

OEM Subaru splash shields are synonymous with quality. To be more specific:

  • Subaru makes its splash shields with durable materials. These materials can withstand moisture, extreme temperatures, and impacts.
  • OEM Subaru splash shields have the correct dimensions. That means OEM splash shields fit well and provide 100% coverage.

Aftermarket splash shields aren’t quite known for quality. In fact, they’re pretty notorious for being cheap. You would be hard-pressed to find a high quality aftermarket splash shield because:

  • It’s common for aftermarket manufacturers to use low-grade materials to save money
  • Aftermarket splash shields don’t always fit right
