My stock Vanagon throttle body is leaking and causing idle issues. Will this GoWesty part fix that, and is it compatible with my existing EFI?

This GoWesty-designed billet aluminum Throttle Valve Housing is a direct replacement designed specifically for our GW-EFI system. It completely eliminates the wear issues found in original 30-year-old throttle bodies, which often cause idle problems. Its sealed ball-bearing design and robust construction prevent the bore ovalization and throttle plate drag that plague stock units, ensuring a much more stable and reliable operation. This part is *not* compatible with your original Bosch Digifant/Digijet system, but it's the perfect upgrade if you're transitioning to the reliable GoWesty Fuel Injection Replacement Kit.

I'm upgrading my Vanagon to the GoWesty Fuel Injection kit. Does this throttle body come pre-adjusted, especially the throttle position switch (TPS)?

Yes, absolutely! We've pre-adjusted both the throttle position switch (TPS) and the throttle plate stop right here in our shop during assembly. This means you won't need to worry about delicate adjustments during installation, saving you time and potential frustration. It's ready to go when you are, ensuring a smooth integration with your new GW-EFI system.

Is this GoWesty throttle body street-legal and smog-compliant for my Vanagon, especially in California?

Yes, this GoWesty-designed throttle valve housing is fully street-legal and smog-compliant in all 50 states, including California. It has received an official California Air Resources Board (CARB) Executive Order #D-786-1. You can have peace of mind knowing your Vanagon's EFI upgrade meets emissions standards.

What makes this GoWesty throttle body so much better than the original stock one on my Vanagon, besides being new?

The main advantage is the complete elimination of wear and tear inherent in the original design. Older throttle bodies have the throttle shaft riding directly in the housing, leading to ovalized bores and a throttle plate that can drag. Our GoWesty unit features a billet aluminum construction with a sealed throttle shaft supported by double-sealed, stainless ball bearings, not just bushings that wear out. This durable design ensures consistent performance, especially at idle and wide-open throttle, and eliminates future wear problems.
