Do those turbonator things actually work they r in like every car magazine and commercial

 

Your better off taking a stinky **** in your intake... lol

 

Turbonators actually do (or did) work --on cars manufacturered in the 60s and early 70s particularly large displacement V8s with relatively small carbs on them (e.g.,400 cubic inch V8 with a 2 barrel or very small 4 barrel carb on it). They caused additional turbulence of the air fuel mixture as it plunged into the intake manifold, which helped mixing of the intake charge, and yes, there were studies and proofs that they did add a tiny bit more power and a just noticeable improvement in fuel economy (and probably reduced emissions, which no one measured back then). Manufacturers did not put them in at the factory largely because they would often greatly increase intake "flutter" noise -- can't have dad's Oldsmobile making farting noises all the time.

But on a modern fuel injected engine, there is no air-fuel mixture to mix up with turbulence: air running down the intake maniufold runners is just air alone, with the fuel is injected right at the intake port, so all turbonators do is add additional and unneeded swirl to the raw air as it rushes through the intake manifold, potentially actually slowing it down and hurting performance.
