Frequently Asked Questions

Brand: Lingenfelter
SKU: L460340004


The STOV-004 is a vehicle speed based switch that can be used to enable or disable devices based on vehicle speed, much like an RPM switch or RPM window switch but instead based on vehicle speed. The STOV-004 also provides a 0-5 volt analog output corresponding to vehicle speed than can be used to provide a vehicle speed signal to many other add on devices. The STOV-004 can accept the vehicle speed output signal from most engine control modules and can also connect directly to many common speed sensors. The STOV-004 can also provide a stage/gear shift output for boost controllers and other devices that need to see a gear shift position switch output to change stages

Dropped off my 2022 Subaru WRX for Exhaust, spoiler, aeroflow dynamic kit, and they killed it. Quality work and amazing customer service. Speedzone gets you right.

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!

Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Thank you all for the amazing customer service.

My favorite place to go for anything car related, they have anything you could imagine & more. The people who work here are the coolest and most helpful people I’ve yet to meet at a car shop. They also don’t try to force sales on you and they genuinely help you with what you’re looking for, 100/10 shop!
