Juice is not for everyone indeed
Also, I'm not offering a "push button" application
I do know the aftermarket claims and prices do not always offer that copesetic levity.
I've been onvolved in this for a short time now, but know the reality versus market gullibility.
Intakes are usually best, stock. Unless what is being offered is a true CAI. Not just a snap on filter or a cone that looks neat.
Headers and exhaust offer MINUM Gains as do the CAI's.
If you seek a 13 second xB... you will need a lot of work, or a juicer.
If you seek the best handling Track Scion ever... Talk to me.
There is more to life than HP. And a properly set up Scion with MINIMAL HP Gains can out run an insanely modded Scion. And all for less $$
