Review on Enhance Fuel Efficiency with Koauto Compatible 4/set Fuel Injector Nozzle 🚗 for VW ALH TDI Beetle Golf Jetta 150 P502 Mk3 Mk4 94-04 by Shane Mack

They are cheap. That's the best thing about them. Performance has improved significantly but will be limited in the low end, once the engine is above 2100 or so the performance will be good. After about 20 weeks I started putting two and two together and tracking my fuel economy, I got about 32mpg or so using a medium duty car. Fuel in the car and that is why the smoke is gray and black all the time under light to medium acceleration. I order pp764 and put them on, and they are about three times better, there is no smoke at all, just more than 3.5 thousand sheep for it. The mileage is back to normal. Give it a try if you don't care about fuel economy, but I've already spent about $100 in fuel on it in 20 weeks.
