JayKo Per4mance

Here at JaykoPer4mance we cover a wide  variety of mechanical repairs. With years of experience we get it done right, the first time. ​​ "If your car don't go, take it to JayKo!"

I started Jayko because I wanted to be able to use my knowledge of vehicles to help people get quality work, for a good price. I truly love cars and trucks, and I love to keep them on the road.  Have a neglected classic that hasn’t seen the road for decades? I can help! 

​​​As a result I went on to become an ASE certified master technician, as well as gaining several I-Car certifications, and GM, Toyota, and Lexus factory certifications. While working in the Industry, I have also enjoyed Drag racing, Autocross, and Rallycross. With this love for racing, I have been modifying vehicles for years, and I especially enjoy building forced induction systems.  I have owned/ raced Turbocharged vehicles since 1996, and have had lots of experience with superchargers and Nitrous as well. 

​Hi I’m Jay Kurth, owner/operator of

Jayko Per4mance.
I’ve been involved with cars basically since I was born.  My Dad rebuilt wrecked or rust damaged cars, built custom cars, and motorcycles.  He did every aspect from mechanical, upholstery, body, and paint. I grew up learning these skills.
