Engine Motor Transmission Mount Set Compatible with 2003-2008

In this review of the A-Premium engine motor transmission mount set, the bottom line is clear: this 4-piece kit is aimed at owners of 2003-2008 Toyota Corolla, Matrix and Pontiac Vibe with the L4 1.8L engine and automatic transmission who need a full mount refresh without paying dealer prices. The reviewer found the set delivers solid vibration reduction and restores driving refinement, especially when the original mounts showed cracking or excessive engine movement. It is a practical, value-focused replacement set that meets OE reference numbers and includes front, front-right, rear and transmission mounts.

Key Features

• Vehicle fitment: Designed for 2003-2008 Toyota Corolla, Matrix and Pontiac Vibe L4 1.8L with automatic transmission to ensure compatibility with common chassis variants.
• Complete kit: Includes front motor mount (A4219), front-right motor mount (A4221), rear motor mount (A4220) and transmission mount (A4218) so you can replace all engine support points in one job.
• OE reference alignment: Matches a long list of reference numbers such as EM9155, EM9164 and 123050D023 to make it easier to confirm parts against the originals.
• Durability testing: Built and tested to meet or exceed OE specifications, aiming to reduce premature wear and maintain engine position under load.
• Warranty peace of mind: Backed by a one-year unlimited-mileage guarantee from A-Premium for reassurance after installation.

Who It's For

The kit is best for DIY mechanics and independent shops performing a full mount replacement on a 2003-2008 Corolla, Matrix or Vibe with the 1.8L automatic powertrain who want an economical alternative to dealer parts. It suits owners who prioritize restoring engine stability and reducing vibration without sourcing individual mounts separately.

It is less suitable for those who demand heavy-duty, oversized aftermarket mounts for motorsport use or for vehicles that have been significantly modified; some customers reported that build heft is mixed compared with OEM and alignment can require patience during installation.
