Well first impressions on this kit I love it!!! Quality is unsurpassed. After just messing with the afr I cannot believe the throttle response and more than that the throttles resolution I cannot wait to get on the track with these things. Honestly it feels amazing I would highly recommend this kit to everyone that has or is close to having full bolt ons. It really just makes the car more fun to drive and the throttle feels less numb to input and lets u really connect to the car like the more you ask of them the more they give u as compared to stock it's night and day. 5 out of 5 quality and the people behind it stand with there product.

Unboxing the new Big Bore 70mm Throttle Bodies showed that EPS took great care in packaging their product. Each TB was nestled in perfectly into its own cut out area so that the product would not be damaged in shipping. EPS provided clear and concise directions in digital format, .pdf, explaining multiple installation options with different common manufactured Cold Air Intakes (CAI) such as AEM or Z1. My particular setup uses Z1 CAI’s paired with EPS TB’s. Upon completing the installation my MAF’s needed to relearn which caused a high idle and a check engine light. After the relearn, my CEL went away and I was left with a crisp throttle response due to the extra air velocity generated. A notable grunt of extra power was served up with my first driving experience with the BB TB’s throughout the entire power band. All-in-all I am very happy with the 70mm TB’s and I’m excited that there are even options that can be paired with my setup considering that my upper and lower manifolds have not been touched prior to this modification.

Got this throttle body kit for my g37 with stillen gen 3 intakes and they work like if they needed to be there from factory. Easy installation but make sure you go to the dealership and buy all the necessary hoses from both throttle body's cooling system if you still havent change the clamp factory tighters the hoses tent to brake when you unplug them. They are cheap at dealership and come with bends special made for your car. Soon as I fix that problem my car was ready for the relearn process and of we go and test this bad boys on the road just to see if everything is working fine. I'm surprise in they way it makes my car response and gets up to speed. I'm currently running a tune just for intakes but waiting for my uprev standard purchase here as well.

Wonderful bigger better throttle response. sounds deeply when I turn on car, and when i drive it. Can feel the difference at what ever rpm range i'm at. Got a chance to fully step on the gas all the way and oh my oh my i might say. highly recommend this to anyone who is trying to look for some serious performance upgrade. Easy installation with minor modifications if you have stillen gen 3 intakes or Z1 they look about the same. Shipping and handling is very fast and convenient, all of their items come securely and nicely package and this one by far is the most secure item I have purchase from anywhere.
