What is the main purpose of throttle body shaft seals?

Throttle body shaft seals prevent unmetered air from leaking into the intake manifold around the throttle plate shaft. This is important for maintaining the correct air-fuel ratio and ensuring a stable idle.

When should I consider replacing these seals?

It's best to replace these seals when you are cleaning or rebuilding your throttle body, especially if you notice rough idling, inconsistent idle speed, or performance issues that could be related to vacuum leaks.

Do these seals come with any other parts?

This part includes the throttle body shaft seals only. You may need to refer to your vehicle's service manual for specific installation procedures and any additional hardware or tools required.

Product Details

BLOX Racing is known for making parts that help tuners get the most out of their vehicles. If you're working on the throttle body of your 2003-2006 Mitsubishi Lancer, these shaft seals are a small but important part of the job. They help ensure a tight seal around the throttle shaft, which is critical for proper air-fuel mixture and idle control.

When you're rebuilding or cleaning your throttle body, it's a good idea to replace these seals. Old or damaged seals can let unmetered air into the intake, causing rough idling, poor performance, and potentially check engine lights. These seals are designed to fit right into the stock throttle body, making them a straightforward replacement during other maintenance.
