Honda throttle body base gasket 17175-P5A-004 – Acura TL / RL / Legend

Genuine Honda OEM throttle body base gasket 17175-P5A-004 designed for V6 petrol engines. This gasket seals the joint between the throttle body housing and the intake manifold, helping to maintain stable idle, correct air–fuel mixture and proper engine performance. It replaces the earlier part number 17175-PY3-004.

Application – Acura TL, RL and Honda Legend V6

The gasket fits selected V6 engines in the models below:

• Acura 3.2 TL – 1996–1998
• Acura 3.5 RL – 1996–2004
• Honda Legend 4D – 1991–2004
• Honda Legend Coupe – 1991–1995

Because there are market and engine-code differences between years, the safest way to confirm fitment is by checking your VIN – we can do this for you free of charge.

When is it worth replacing the throttle body gasket?

• Whenever the throttle body is removed from the intake manifold
• When you see traces of oil, dirt or fuel deposits around the joint
• If the engine has unstable idle, fluctuating revs or mixture-related fault codes
• During intake manifold / throttle body refresh or cleaning

A fresh OEM gasket ensures a tight seal without improvisation, reduces the risk of air leaks and saves time compared with cutting a gasket from universal material.

Why choose a Honda OEM gasket?

• Correct material and thickness matched to the original intake design
• Precise fit to the throttle body and manifold – no trimming needed
• Stable sealing over time and resistance to fuel vapours and temperature changes
• Direct replacement for 17175-PY3-004 in the listed applications

FAQ – Honda throttle body base gasket 17175-P5A-004

Does 17175-P5A-004 replace 17175-PY3-004?
Yes. Part number 17175-P5A-004 is the later Honda OEM gasket and replaces 17175-PY3-004 in the listed Acura TL, RL and Honda Legend applications.

Do I need to use additional sealant or silicone?
On clean, flat and degreased surfaces, the OEM gasket itself is sufficient. Additional silicone is usually unnecessary and excess sealant can get into the intake ports.

Can I reuse the old throttle body gasket?
Reusing is not recommended. After years of heat cycles the gasket takes a set and may no longer seal properly. When the throttle body is removed, it is best practice to install a new OEM gasket.

Does this gasket fit all V6 versions of these models?
It fits specific V6 engine codes used in the models listed above. Because there are differences between markets and production years, we recommend confirming fitment by VIN before ordering.

Can you check compatibility with my car by VIN?
Yes – we can verify whether gasket 17175-P5A-004 is correct for your vehicle based on the VIN number at no extra cost. Just send us the VIN in a message or in the order notes.
