The no limit intake kit and my Apex ported intake manifold have made more than one of my customers happy. I would not keep the stock system in either area no matter what the truck was doing. Both the intake and intake manifold have too much to offer
Let me know if I can help
You can leave it plugged in and reading ambient temp with no issues. the temperature change between the two is very minimal. The only time you may see a excessive higher reading is at idle or constant low speeds. Regardless, I do agree that it's better to have it as factory as possible.
