Yes about 30 hp possible for all three. Here is the deal If you have them put on go have the car tuned. Also we have found that the factory sparkplugs are a heat range too high so try one step cooler if you live in a typically hot climate. This is just a suggestion on the plugs. It worked for me to the tune of 8 HP on the dyno on an avg of 5 pulls.

I have seen people do all the above and only gain 10-15 hp because they needed a tune. Remember climate and altitude etc.... affect your cars performance and effeciency so anytime you make a bunch of changes do some tuning. Just a suggestion but a good tuner makes all the difference!!!
