1. Tony Salinas Says: If i add headers,CAI,throttlebody spacer, and catback.How much Hp will i get and will i feel it? also i am adding a front strut tower brace.

2. Julio Lopez Says: Depends on your vehicle, some engines respond better to bolt ons more than others.

3. Vipassana Says: Actually, it's easy to back up what I said. There are THOUSANDS of websites that provide DYNO PROVEN results from the modifications that you listed.

But good job on voting on the only person who agreed with you.

4. Vipassana Says: CAI: None. You have one from the factory. So zero gain.
Headers: Practically none. Maybe 3-4 in high RPM, but for daily driving, zero.
Catback: This is an exhaust that is AFTER all the restriction of your exhaust. So basically no gain.
Throttle Body Spacer: Depends on whether an increased throttle body gap actually does anything for your car. Some cars, it REMOVES horsepower.

And you could have looked up all this info on your own. There was no point in asking this.

5. Stpaulguy Says: Nothing. Really. The only time a CAI adds horsepower is when the throttle is wide open and engine running at or near red line. Even then, the most you'll get is 10-15. And how often do you think you'll be driving at red line. The entire rest of the time you will be getting ZERO additional HP. The largest obstruction in the entire intake system is the throttle plate. No large filter can compensate for that.

6. Tyler Everton Says: Depends greatly on brands and your car. Cheap stuff about 20-25. High end 50-60.

7. taxpayer Says: 20 hp the strut brace will no ad any hp

8. FINN TO THE RESCUE Says: Save this question. Maybe sometime in the future you'll see how ridiculous you sound.
