Review on 🚀 High-Performance MOSTPLUS EV6 Style Fuel Injectors for Crown Victoria 4.6L V8 (Set of 8) - Boost Your Engine's Power! by Kevin Barbon

So I bought these injectors for my 2003 Mercury Grand Marquis in case mine stick together. I had a leak in the upper manifold and when my certified mechanic went and installed them they didn't work. In fact, the car wouldn't even start until those new ones were removed and the old ones put in. When I bought them they were listed as fitting my car and year, which they weren't. Now they don't take them back and give me my money back. Whether the return date has passed or not they would never take my car so I need to get my money back for them. everyone is dissatisfied!
