Autowxjq Set of 6 Iridium Spark Plug and 6 Ignition Coil Pack Compatible with Nissan Infiniti Maxima Murano Pathfinder Quest Altima Q50 QX60 FX35 370Z Q70 G37 QX50 QX70 V6 Replacement for UF550

Just what my car needed! Easy to install, engine rides smoother, seems to be of as good quality as the OEM part. The price is way better than the local stores. Functions better than expected.

Works great so far (3 months) Q50 Hybrid. No misfires or engine codes. Perfect fit.

Fit on 2010 g37 s sedan 6mt perfect. Engine lag is gone in 1st. But when pulling out the old spark plugs (the plugs weren’t too old) I saw oil heavy on plugs on the driver side. Back story , year before I changed valve cover gasket and I saw the spark plug gasket displace as I was putting the valve cover back on. So point of this story , if you’re fouling your plugs with bad plug gaskets and oil getting in new plugs and coils will help but only in short term till they get fouled. Also, these plugs were not quite gapped according to 0.43. 0.44 mm specs for g37. I had to spread all 6 of them all out one by one , gapped them in a pile then put them in the car. Thumbs way up! When dealing with an older car, my thinking was let’s get all new stuff, plugs and coils, but not break the bank in case the fix was a bust. The fix …. So far so great. No more cel no more lag. Hoping oil burn is gone … Long story hope it helps

Fit my Q50 perfect except one of the spark plugs had bad threading. I would of caused 1000s of dollars in damage trying any more to get it in my car. Now I have to take everything apart again at another time which is super frustrating. Thanks for wasting my time

Great fit.
