Hey guys can i install my Grimmspeed intake without a protune? Im stock with just accessport

Good thing you asked first.
Can you, yes. Should you, no.

At least an e-tune but if possible protune is best.

Atleast you asked lol. I would not recommend putting on any intake without the proper tune on the car. I believe even the intructions for the grimmspeed intake state that you require a protune.

The better answer is just don't put an intake on it...no need if there aren't any other supporting mods. Get an K&N drop in filter instead and call it a day.

Getting an intake then a protune is like taking your worn sneakers to the dry cleaner.

I also wouldn’t install it without a protune or etune.

Recently I watched a grimmspeed build video they are currently doing with a 2020 or 2019 STi, and they went directly to get a protune after installing their own intake.
