Yep. The bigger the engine and the higher the rpm, the more HP will show on the dyno (and it will be modest at best).

I agree, especially on 4 cylinder cars, intake and exhaust will be modest at best.

On GM's 4.3 engine with distributor ...up to at least 2001 model as I had, Put on an MSD Ignition, HP distributor module, rotor and cap. Next add MSD ignition coil and Taylor (or a good set) of wires. Then put in AC Delco Rapid Fire or Bosch +4 sparkies. I did this and GAINED 5 MPG highway and Dyno'd 28+ HP! I then added Hypertech Power programming due to having to put on 245/50/15 tires and traction bars to get needed traction on dry pavement...not to mention wet.
In all the MSD ignition more than paid for itself in gas savings the first year I had the S-10, EXT Cab and LS Sportside bed. I just sold it after having it 7 years.
