MAS 1Pc ignition Coil Pack Compatible with 2003-2008 Infiniti FX35 G35 M35 Nissan 350Z V6 3.5L Replacement for UF401 C1439 22433AL615 5C1430

Perfectly fine

I was skeptical to purchase this but figured for the price and knowing I only needed one I'd give it a try vs spending around $70 for one. Works perfectly and hasn't skipped a beat so far

My 2005 Infiniti G35 had been becoming progressively sluggish for the past several months which I couldn’t track down the problem. The car started cutting throttle under hard acceleration about a month ago and worsened to the point that pushing the accelerator pedal more than a 1/4 of the way would cause the car to act like it’s at rev limit. The whole time the car never had any codes indicating a malfunction, while using high dollar diagnostic scanners. I had replaced the intake tube that had a small crack, cleaned the throttle body, the MAF sensor, did the ecu relearns related and still no improvement. A few days ago while getting on the highway the car started to misfire hard and motor was shaking. Stopped the car and turned off the ignition and restarted it and the car stopped shaking but started again shortly after. Even then the car didn’t have a code yet when scanned. I suspected valve gaskets by this point but after a few miles the CEL was blinking so I knew I’d have a misfire code at this point and sure enough P0305 (cylinder 5 misfire) and P0300 (general misfire) which then prompted me to pull the ignition coil and spark plug to inspect and sure enough there was a scorch mark on the coil. I ordered this coil with expectations that it’ll solve my misfire problem only and when it arrived yesterday I installed it promptly and let it idle for a bit and it ran smoothly. When I got it on the road and hit the gas I took off like the car was new again. No misfire but also no fuel and throttle cuts I was dealing with previously. So far it has only been about 24 hours since fixed but if it holds up I’ll soon order more to replace the others when I replace the plugs. They say you only replace the coils as they fail individually but the troubles I was having and the searching in the dark for the solution I think I’ll go ahead and be proactive here. Super easy to swap takes about 10 minutes to swap the one out. If doing all 6 and it’s your first time I’d say 1.5 to 2 hours should be more than enough time to complete on an Infiniti or a Z. Not sure about the fwd cars that use these.

I bought and installed one coil which worked great to fix the engine light warning and then two more just in case, all three for less than $15 each. Before I realized that Amazon sold perfect replacement coils for my 22 year old G35, I had bought three replacement coils from AutoZone and O’Reilly for $68 and more each in the last two years when the first three original coils failed. The engine runs like new with these coils. I now realize to always check Amazon for replacement parts for my vintage beauty.

Worked good.

Perfect fit, and so far so good.

Fixed my ignition misfiring problem for #5 cyl on my 2004 Nissan 350Z.

Good part been driving for 3 months with no problems

utiliser pour un 350z 2003 tout semble aller pour le mieux !!!
