In 2005, yes Honda would have done it. But 10 years later, you would think someone would have come up with something. I'm still curious if they actually work in other makes. It's like cop cars. Some have different gear ratios and performance chip from the factory. And this has been ongoing as long as I can remember. Maybe they should borrow the crown vic motors from Ford and put them in RLs. Just kidding, but just saying..If you could improve your hp by 10 and fuel efficiency by 1-2mpg by simply adding a different air intake or simply electronic device, don't you think Honda would have done that from the factory?
