Detailed Description

Motorad MO209 is an engine oil filler cap engineered for specific Subaru WRX and Subaru Forester applications. Manufactured from quality components by an OE supplier, it is built to provide proper fit and sealing at the oil fill point, helping maintain oil containment and engine compartment cleanliness. The standard replacement design measures 2.21 in. by 2.21 in. by 1.88 in. and uses a 1.63 in. male thread diameter.

This part cross-references OE-style applications such as 703-2323 and 15255AA141 for the same use case. For buyers searching for a Subaru WRX oil filler cap replacement or a Subaru Forester engine oil cap, MO209 provides a direct-fit option with a finished yellow appearance.

What It Helps Solve

  • Loose or damaged oil filler cap sealing
  • Oil loss from a worn cap or seal
  • Broken, cracked, or missing filler cap
  • Hard-to-read or faded cap indicator markings
  • Incorrect fit from a non-specific replacement cap

Installation Notes and Tips

Verify thread diameter and application before installation. The cap uses a threaded male design and is intended for specific fitment, so it should be matched to the vehicle listed above. Inspect the sealing surface and gasket area during replacement to confirm a clean, secure seal.
