2 PCS Automobile Power Upgrade Fuel Saving, OBD2 ECOOBD2 Automotive Plug and Driver Single Plate, Automotive Energy Saver Accessories, Universal for Most Cars (Green)

After a couple of weeks using this product and one of my trucks I could tell the different thin gas gaining about 3 mi extra to the gallon in a V8 I recommend trying it

If I could make zero stars...Total Scam!I have examined the device fully. There is no actual connection inside between the vehicle and the device except for power and ground. These are used to power the lone IC inside, which is a cheap LED driver used to "light the pretty lights" (3 LEDS - 1 red, 1 yellow (flashing for effect) and one green). There is no way for it to communicate to the car, therefore there can be no benefit of any kind (except to line the pockets of the seller of the device).

As described. Good value

Notice a big difference in my gas usage.

I put this my girlfriends 2019 Toyota Camry and instantly noticed the idle was smoother but the power performance was very noticeable. I drove 284 miles from San Diego to L.A. Getty museum and back. My average mileage prior has always been 28.9 mpg, after the trip it dropped to 28.4 which it has never fluctuated like this in 3 yrs. I use cruise control most of the fwy driving so that peaks for itself. My opinion is there is no value dollar wise, the value is clearly your vehicle runs smoother and is more powerful. It was so easy to install and it appears to be very well made but the real question is how long will it last and will effect the vehicles computer long term....

Complete Scam ! After ordering my son looked it up in Google for reviews. Two engineers reviewed said item and mentioned no effect on connection to the computer. I have had it connected for a month now with no increase in mileage what so ever. SCAM item. Need to work a refund for me !

Great product and price. Great Fit.

I only just put this in my car a week ago. I’m not really sure on how affective it is yet. I will update but it’s cheap enough to take a chance. I bought the 2 pack. Gave one to my youngest. I’ll get her input also
