Just got them installed in my 85 corvette the work perfect and my mileage has increased by at least 3 to 4 miles a gallon. They shipped super fast I think I had them in 3 days or less. I will always buy from CS from now on.

Had an issue with 2 out of 6 injectors received. CS Performance Injector took care of the issue in a timely manner with no questions asked. Injectors flow nicely and gas mileage is great! I recommend this seller 100%.

Manufacturer assured me of proper fit. Kit fit my injectors perfectly, (O rings and filters). My car's performance is improved greatly after cleaning each injector and replacing each injector filter. See filter comparison in photo. Old filter, removal process can separate ring from unit, on left. New filter, complete, on right. Looking forward to repeating procedure as soon as my mpg drops again.

I got 6 of the remanufactured fuel injectors for a 2009 Mercedes R350 with 185000 miles on it. These were just what I needed, the engine runs like new and has a smooth idle and lots of power. A data sheet came with them with the test results for each injector too, I will shop here again when I need replacement injectors A+.

I ordered a size to big of injectors and was running rich. I asked for an exchange and CS sent me the exchange no problems no hassles and even credited me for the price difference! I installed the new injectors and the truck runs like it should, feels strong again and regained throttle response. No more sputtering! I highly recommend CS Performance injectors!

I purchased injectors for my 2004 Ford mustang GT about a month ago from CS Performance Injectors. I opted for their 1% flow match injectors which where $80 more than the standard injectors which are pretty close flow matched anyway but I figured why not it came with the flow match print out. I will say the packaging was awesome they looked great but what I wanted was to see the Performance I was blown away at how much horsepower I gained and torque. The car has never run better, smoother and the throttle response was better than the car came out new. I never expected that much of a difference. I will be using these folks for all my future injector purchases and I highly recommend you do too. You won't regret it. Seller workmanship.

My car runs smoother and more powerful after replacing the fuel injectors. Their price is reasonable. There is also a discount if you ship the core back.

I got a set of 1% dynamic flow-matched rebuilt injectors from CS performance for basically the same price I was paying replacing my old injectors piece-meal as they failed with injectors from my local parts store. It would’ve actually been cheaper to buy this set instead at the first injector failure. On installation I saw an immediate jump in fuel economy from 16.5 to 20.5 combined. In my case, the injector set will pay for itself in 5-6 tanks of gas. I’m a big fan, I’m going to try to get a set for every car I buy going forward.

Great experience with this company! Did the #703 injector upgrade on my 96 Jeep XJ 4.0. First time ever doing injectors and it was a good experience. The injectors fit perfectly into the fuel rail and even the retainer clips lined up on each one. Can feel the difference especially with idle smoothness and quicker startup. Direct fit plug on the connectors was nice as well. Hopefully I’ll pick up 1 or 2 mpg upgrading from the oem single hole to new 4 hole for more efficient fuel atomization, but even if I don’t I’ll still be happy with the smoother idle. Glad I found this company that offers quality products at reasonable prices. Would definitely recommend after my positive experience.

I had excellent service with CS Performance. Had a small glitch on some upgraded injectors but CS quickly remedied the problem. I was very impressed by there response and solving my problem as well as quick delivery. I would definitely use CS performance again and I highly would recommend this company for quality fuel injectors.

Bought 6 refurbished flow-matched Bosch fuel injectors for my 1990 Bronco II. They came very quickly and were the identical units to the originals. Although the car was already running well before I installed the CS Performance ones, they really made a very big difference; the truck now pulls strong and smooth throughout the rev range. The CS Performance injectors are the real deal; highly recommended. Also, the price was great, best $60 I have spent on this truck, more than worth it.

These folks are great, I told Anne Marie ( customer service ), that I wanted a set of their 1% injectors for my truck, she said they could do that, then I told her I needed them the next day because the truck was fixing to go on a trip, she said they could do that, and they did. I bought the injectors on Wednesday and installed them on Thursday ( in Tennessee ). I got a couple of buddies with trucks like mine, we'll be ordering a few more sets. I've owned this truck for about 7 years and it's never run this good.
