Installed on my S5 to help with *temps*, I have to say it works amazing. Going over regular Dual Pulley 3.2 PR on the cars they create a huge amount of heat and this kit works wonders for 3.5 PR. Awesome product with instructions, I'd say almost anybody with basic mechanic skills should be able to install this kit. Message me anytime for questions.

I have been purchasing these water methanol kits for years now and been installing them on various cars here in Tanzania. I must say they are very reliable and easy to install, works accurately with the internal boost sensor. They are a very good product to make quick power with pump gas in places where we can not get racing fuel or if your in a budget mod. Must get product.

This is a good product, however a little expensive I suppose. I run water injection on my 7.3l diesel powerstroke to keep the egt temps down. without the water, I can't safely use my available horsepower. The problem is algae in my distilled water tank. My jets would clog on a trip from LA to Vegas! This filter mostly catches the algae thus extending the jet life. The screen filter will load up with algae, but i can hose it clean on the road. Mostly this filter solves the algae problem. For the record, old B52 jet engines injected distilled water, and yes, algae clogged jets was a BIG problem. There is nothing new under the sun. Cheers!
I actually bought this for my 6.5l twin turbo diesel Despite the fact it will lower iat and egts i already have really low iat and egts but ive heard this will help increase power since this comes with different nozzle sizes and a controller i should be able to increase my horsepower and help with power band and turbo lag issues besides all that kit comes in a nice package looks to have every piece needed for the install i totally recommend this kit to anyone
Got This more for lowering intake manifold temps due to living In a high heat high humidity area. The tank that comes with is kind of a pain to figure where to mount if you don’t want to screw into your seat. With this v3 downside you can’t run straight methanol you have to mix, but it’s not a terrible trade off if you are using for knock protection and for lowering intake temps more than methanol alone can do. Overall nice product and with a pretty straight forward install.
I cant exactly recommend this product yet being I lack the injector nozzle of having it completely installed! Any suggestions on a replacement would be greatly appreciated!
I have learned through tuners and enthusiasts that this kit has issues. The nozzle fails consistently after a few months. So I went a different route and found that another brand is far superior.
Very happy with MAPerformance,I received the kit very fast, I'm disappointed with the mounting points on the controller it's not designed to be mounted in any easy way, it should come with 2 threaded holes to attach it, I'm also disappointed that you pay almost 500 dollars for a kit, then have to buy an additional filter and meth solenoid another 80 bucks. When I received the kit I took a peak inside the box to see that the controller was separated, the backing was not attached to the controller and the supplied screw would not thread into the back, had to buy a rubber nutsert to thread the screw into the back. The wires are great, nice and long easy to hook up. Enough nylon line to run about anywhere you need. I would recommend this kit to anyone. Haven't actually ... MoreVery happy with MAPerformance,I received the kit very fast, I'm disappointed with the mounting points on the controller it's not designed to be mounted in any easy way, it should come with 2 threaded holes to attach it, I'm also disappointed that you pay almost 500 dollars for a kit, then have to buy an additional filter and meth solenoid another 80 bucks.

(I can not speak English Use Google Translator) This product is really good My car is a Genesis Coupe 3.8 Twin Turbo Vehicle 520hp 61torque Before we installed this product, the engine was too hot. Other engine knocking Intake temperature rise The weather was so hot that I fitted it. And I rerun the mapping. Currently my car is 780hp 101torque and the condition is very good I will use this product in other cars as well.
