Sorry to burst your bubble, but you won’t. Your only difference will be sound.
Electronic throttle opening will not respond better as factory pedal mapping is extremely slow on Gladiators.
Your air intake temps will likely be higher which will pull timing and throttle body spacer does absolutely nothing. There’s a recent post on here that shows as much as a 12 HP loss with cold air intakes on these, proven on the dyno, and I see it in tuning all the time.
For what you paid on those mods you’d be at least halfway to a custom engine and trans tune, which is the best way to add power, torque, and response on these. I’m one of the only companies doing them. I’ve got a thread on here and the JL forum that covers more if you ever feel up to it.
While I currently don’t have a CAI, on my latest a 24 Gladiator 3.6. I have used K&N CAI systems on others, that depends upon the vehicle you have. Some like the 5.3 in a 2005 Avalanche I had responded well, with an extra 1-2 mph city and highway respectively, with better response, but that’s because the engine cover on that generation and most GM TRUCKS use, have the intake runner from the air cleaner to the throttle body run through extra baffles and tubes to lower intake roar, that especially when compared with the K&N system will create resistance, resulting in dyno proven power and efficiency losses, on those particular vehicles. Now under the hoods of the Jeeps, there are no covers, with extra passages and baffles, just a fairly unrestricted tube, from the air cleaner that incidentally have two air intakes, one down at the front of the grill, the other up top semi sealed or isolated from the under hood heat, by drawing from the generates behind the headlight. The only area of resistance that can be addressed is the smallish sq “ flat air filter itself in the air cleaner box, instead of a conical filter that has more surface area.
