Rostra Precision Controls, Inc. is the Original Equipment manufacturer of vacuum modulators. Rostra Modulators are the highest quality in the industry. Complete and universal, problem solving designs, function perfectly the first time, every time.
I installed the Rostra vacuum modulator in my 2003 Honda Accord, and it works like a charm. The black stripe design looks good under the hood, and it was easy to push in. My engine runs smoother now, really happy with this purchase!

Not impressed with the performance
I bought this Rostra modulator hoping to fix some vacuum issues, but it didn't really help much. It fit okay, but I expected a bit more from it. Maybe it’s just my car, but I'm a bit disappointed.

Easy installation, good performance
Installation of the Rostra single push-in type modulator was straightforward, and I'm pleased with its performance. The black stripe gives a nice touch, and my vehicle has been running better since it was installed. Definitely worth it!

Perfect for my classic car restoration
I used this vacuum modulator for my vintage Mustang restoration project. The black stripe adds a nice aesthetic touch, and it fits perfectly without any issues. It's working great so far, really happy with it!

Decent product but some issues
The vacuum modulator does its job but took longer than expected to arrive. The packaging was a bit crushed, which worried me, but thankfully the product itself was fine. Just wish the shipping was faster!
