Will adding tuner, cold air intake, and throttle body harm stock 3v 5.4?
Hey guys, I have a stock 2008 f250 3 valve 5.4. Only real modifications are a cat back exhaust Flowmaster super 10 with duels coming off the flowmaster. I'm looking to add more power, efficiency, and torque to my 5.4 so I've been contemplating getting a Sct tuner, S and G cold air intake, and a air aid throttle body spacer. While this sounds all fine and dandy, will adding these to my stock 5.4 harm anything within the engine/drive train? Is there anything else I need to add with these other modifications to make everything work and run correctly? Last thing I want to do is think im adding all these benefits to my engine and wind up just hurting it. Any input is appreciated thanks.

Sorry I just seen you said F-250 Air Intake probably won't work but the Tuner looks like it might!!

dude, truck's 11 years old. I'm thinking if anything was gonna happen now, it's gonna happen regardless of adding a tuner and intake.
As for a throttle body...…….i'm not sure that's even necessary.

Throttle body spacers are absolutely useless. Some aftermarket air intakes have been known to cause the 5.4 3v to run extremely lean so be careful, and tune it properly.

Noted, I won't waste my money on the throttle body spacer👍 I've also heard alot about aftermarket cold air intakes messing with the 3v that's why I researched quit a bit and from what I've seen/read on these forums the s and g cold air intake seems to pair good with this engine.

Not gonna hurt it, but don't expect miracles from the intake

Does the GOTTs mod work for f250s? Since you're on an F150 forum in the general section, I assume you made a typo and meant F150. Regardless, look into it, it'll save you money if you're looking for more airflow. Not sure how much of a difference either will make though.
For what it's worth, you already have a cold air intake. For like 50 years now all vehicles have came with them from the factory.
