Review on Pack Of 4 Fuel Injectors 16600-86G00/16600-86G10 Replacement For Nissan Pickup D21 2.4L 1990-1995 JS2-1 by James Mayfield

I bought these in October 2021 because my gas MPG was very low, averaging around 11 to 12MPG.The millage did not increase but instead kept going down. By December it was down to 10mpg and still falling. When it got to under "7" and with the gas prices way over $4.00 per gallon, I wasn't driving any where unless I really had to.I finally decided to but the old ones back in and immediately my gas mpg went back up to 13.Mind you it's not the "18 around town" it had when it was new, but still a lot better.Not sure if the 4 I bought were lemons - or if the brand is just bad.
