Need Help Apexi Air Intake Is It Harmful For Stock Fd?
i consider short ram wise for an untuned setup. the real danger is the intakes taking in cool air while still running on the base map. really cool air = less pressure = overboosting.

The stock airbox can be modified to flow really well, and bring in cold air.

the stock ecu doesnt want to see any boost increase over 10psi. unless you have a decent cold air setup and your driving in 40 or less degree weather, you should have nothing to worry about.
The stock ECU does not change it's boost control settings. So if you add (for example) an intake, downpipe, and muffler, your boost may increase from 10psi max to 11.5psi. It usually takes about 3 flow mods to cause this.* Just installing an intake on a totally stock car will probably not increase boost at all. If your boost ends up above 11psi at all I recommend installing some boost control upgrade to dial it back down to 10.
*A midpipe (catless exhaust) can drastically affect boost levels - I recommend upgrading all the other stuff before installing a midpipe.
The stock ECU is limited to 12psi, then it cuts fuel. (If you have the high output 99+ model it's a little more). While fuel cut won't harm the engine, it's annoying as hell and sometimes the fuel cut doesn't enact fast enough to prevent detonation. Then it's pretty harmful.

you will def see a change in intake temps. yours right now are, if you think about it, serving little to no purpose. cept for louder spool. short ram intakes on fd's are alot less effeciant then they are on naturally aspirated cars
