    Never knew this company existed only 15 miles from me. Dropped them off and Keith said they would be ready the next day. Very impressed with the quality of work and the accuracy of the test flows. I now understand why this company has customers throughout the world. If I ever need any injector work this is where I am going.

    Took my husband’s injectors for an annual maintenance. Very easy to work with, and he was very knowledgeable about our injectors that needed cleaning and tested. Keith took care of my husband’s request quickly and had very fair pricing. He also provided injector flow rate and timing data. Highly recommend!

  • Steve Slandzicki

    Well ran business that does what it says. Keith openly shares knowledge and is willing to walk you through the process and explains exactly what to look for when trouble shooting. I am greatful for his and company experience and expertise. All promises kept. Value is 150% of what you pay for.

    These guys are awesome! Sent them my injectors, they called within 2 days and said one of the injectors I sent wouldn’t work so they threw in a used one they had rebuilt for me free of charge (and returned the one that didn’t work). I will definitely be using their services again. Don’t buy Chinese bootleg OEM injectors on eBay or Amazon that only work for a few months, get the originals rebuilt, you know they worked, they will make them better than new!

    Amazing experience dealing with Keith at Injector Experts. Extremely nice guy, easy to work with, and by far the most detailed injector reporting I have ever had from a cleaning/ flow test service. Quick turnaround, very nicely and safely packaged all my injectors. I would highly recommend Keith to anyone looking to get their fuel injectors serviced!

    Injector Experts is the only place I will ever get injector service done. Keith is awesome at what he does and is the most knowledgeable person I've ever met. He answers every question I have and I can't thank him enough

    Injector experts is great Keith helped me get my twin turbo mustang running right after he flow tested my injectors and found a few bad ones. He personally talked to me about the industry and the nature of his business. I learned a lot from him and it’s not often you meet such a willingly helpful person in this industry. He is very budget-friendly as well, I will definitely be sending my injectors to him every winter to get cleaned/gone through

    Great place, Great service. He got my fuel injectors cleaned great and was very quick about doing it. Definitely would come back here for any injector needs.

    ⭐⭐⭐⭐⭐
    Keith is awesome. Extremely knowledgeable about injectors. Saved me a ton of money over buying new injectors for my mercedes by cleaning them and being one of the only people able to clean them properly to my tuners specs. His prices are beyond fair and his turn around time was spectacular. A true gem for racers and people needing to save a little money by having their injectors cleaned instead of replaced. I cannot reccomend Keith and his shop enough. I will definitely be back to keep up on my race cars running e85 because his service is incredible. A++++++ Keith thank you sir!

    I have been using Keith for a few years now introduced to me by another great location for motor builds in San Antonio Kotzur Racing heads, Matt and he does a fenominal job, cleans the injectors and gives you anreport on each one for quality level and status. I have recieved a few returned that were bad but better than putting them back in your car and running it especially when you are using them for HI performance! Like me. Hi recommended and turn around is great as well as pricing. Ship them to him. You wont be disappointed!

    Anyone who needs electronic injector work, call Keith. He just went above and beyond for me on my Mustang 5.0, fixed the problem and turnaround time was amazing. This is one of the best companies I have dealt with in a long time. Thanks again, Keith!

    For those reading this review, I used to race cars (back in the day when they were still carbureted!). I spend a lot of my time now doing restorations. My latest project is a 2003 Subaru Baja. My journey in that endeavor led me to Keith at injector experts!

    Keith is the collision of old school knowledge with modern technology! What a treasure! Trove of knowledge and experience working in today's high technology racing. I brought some old fuel injectors to him off this Subaru that were stock. I didn't want to put in aftermarket injectors. Keith fully disassembled the old injectors and made them new again! Talk about service... I tried to save a few bucks and drop them off to him while I was working. He dropped everything from me and got them done in a matter of a few hours! I can't stress enough how much he has a customer for life in me! I'll never buy another fuel injector again! Unbelievable service and quality at a very very affordable price!

    You can't go wrong with injector experts! If you're a racing professional, a. Tuner, or a weekend car guy send your work to Keith! He's a mystic!

    If you need your injectors cleaned, you can trust Injector Experts. You'll meet Keith, an honest man who knows what he's doing. He got my injectors flowing properly which fixed my erratic air/fuel ratio and idle leaning. Not only that, he explained what was happening, why, and gave me a demonstration of my injector's performance and showing me why doing it myself with carb cleaner ended up being a temporary and improper solution before giving them back to me. On top of all that, I dropped them off in the morning and he was very sorry to tell me his power went out due to inclimate weather. He then called me 6 hours later to let me know the power is back on and he had my injectors cleaned and ready 45 minutes later. I couldn't ask for better service.

    I had an amazing experience dealing with Keith at Injector Experts. He is a very nice guy and was able to explain to me the importance of getting injectors cleaned and flow tested as well as explain all the data from the tests. I dropped the injectors off on a Wednesday and picked them up just two days later. He also told me exactly what portion of the data I would need to use in my tuning software and gave me some good resources for tuning in general. Overall a great experience and I will continue to go there in the future.
