Stock 1.4T injectors are standard length 33# injector with an EV1 plug. This is the most common style of injector. As you add mods to your vehicle, eventually you will need to upgrade the injectors. The stock injectors max around 180WHP and are sufficient for all but the most heavily modified stock turbo setups. How far you can push a stock injector is based on the fuel blend in your state so it can be a good idea to upgrade if you plan on a lot of bolt ons. 

42# Bosch Green Giants will support up to a ZZP V3 on E85.

Be careful where you buy this injector as most of what is sold out there is actually genuine Bosch. The problem here is that only the Bosch injectors work in the sub 2ms pulse rate needed for proper idle and tuning on a small motor. If you have idle issues and run an injector that looks like this, that is often why.  

PCM programming is required whenever your injector size is changed.
These injectors are plug and play and do not require any adaptors or spacers. They are direct replacement.

While popular, we actually recommend our 60# injectors over these due to lower price and future mod potential, however ONLY if you are running full E85. (link) Due to the size of this injector it can cause rich issues at idle.

Needed and glad I did!

Once Tim sent me a tune and I could put them in it took less then an hour. I didn’t unhook the gas feed line, just drained the pressure before hand and these slid right into place. I was amazed at how the car ran on first startup! It ran better then with the stock setup.

The injectors are working beautifully with the V3 turbo. No stumble at 3k like there was with the stock injectors and turbo. The retainer shoulder is in a slightly different orientation than the stock injectors so you have to pay attention during install.

Good product, I don’t really notice a difference over stock

I run a pretty aggressive tune and these definitely deliver more fuel as I can see by a lower duty cycle, my stock injectors were almost maxing out. After tuning for these I dont notice much difference. Maybe more needed for a bigger turbo setup or E.

Easy install

With a couple videos of watching people install these injectors it was a breeze, they work great with my tune couldn’t be any more happy with the product.
