Is this real?
Where can you buy this?
Anyone tried it?
What is the Turbonator?

 

That will be absolutely useless and eventually becomes a restriction.

Don't give them money, please.

 

I am not sure if you are being serious or not.

However, if you read the last paragraph in the link that you posted they talk about how Popular Mechanics tested the device and other similar devices and there was no measurable difference in power production or fuel efficiency.

 

OP, they are correct. Don’t waste your money on the original Turbonator.

However, the new Turbonator II is a much improved product. It will be 500% more efficient than the original. No installation is required, just carry it in your car. It will be a limited production run for the first 100 lucky people only for a low $99.99. Please send cash – small unmarked bills preferred. But wait … if you order in the next 10 minutes, you also get a Turbonator Sidekick - ABSOLUTELY FREE. Order now.

 

Haha... my friend actually bought one when he still owned his Pathfinder (newer year model than the one my brother-in-law had).

He thinks there was an mpg increase... but at the same time, decided it was useless.
