Von E –
Installed them yesterday the plugs were on the opposite side making it hard to plug in but made it work
Monique Jules –
Replaced crankshaft, exhaust cam sensor and 1 intake cam sensor. The intake sensor is not the same orientation as these 3, but I was able to make it work. The crankshaft sensor has last over a year, where my prior replacement only lasted about 6 months.
