WOW! Install takes 5min, but is proven to gain 30HP, 30LB-FT, and still increases efficiency by 10%? That is literally incredible and unbelievable. They even make one for every car.
These chips are usually the first thing enthusiasts learn about, since they promise the most, cost the least, and are highly promoted. Most DIY car modifications reduce both power and efficiency. Please continue researching, but research fundamentals before the products so you know what to expect. If you're deep into products, chips & intakes & additives are the most highly promoted, and are virtually all scams.
Cheers
edit: I forgot to mention, a scam can easily damage your engine.
