Definitely makes a difference on our 2017 QX50. It now has the power feel of our G35 that I did the same mod to. You may have to cut the short connection on the side of the intake hoses about 1". I sprayed each connection location (not the intake hoses) with WD40 to ease the installation. It's a tight fit so take your time. It's best to remove the plastic engine cover and once you get the hose partially on, use a flathead screwdriver to walk the rest of the hose on. I only wish this was a more rigid hose vs.silicone to eliminate some of the flex during install. Simple, effective and definitely awakens the engine a bit especially when complimented with K&N air filters.

The product is a decent alternative to the real thing, just on one side on my g37 Infiniti has a dust collector so I wish this had 2 side holes on one of the tubes instead of only 1. I hope that makes sense.

Tubes were nice but fitment requires too much modifications. They do not fit without cutting, which I don’t want to do. Luckily amazon accepted the return.

I have a 2015 Q50S, the 3.7 engine. Driver side fit perfectly. Passenger side, had to order another part to make it work. Felt like improved response once installed. Good product for the 3.7 engine to make better air flow.

I used this product on my 08 g35x sedan, and it was some cutting involved nothing serious, other than that it was a piece of cake.. my gas mileage is better I also have K&N replacement filters, it's a nice sound as well, not as loud as a true intake system, but a noticeable difference.

The fit was perfect with the factory ductsas FSR as the angle of the side ports but overall fit good and looked great.

Product is a quality piece. Driver side fit fine ,but passenger side needed about 1/4 inch trimmed off the pcv tube to make it fit properly on 08 G37S coupe. Engine sounds better and you do notice a slight performance gain,but nothing crazy.make sure you have a sharp razor blade and 40 to 60 mins for install .

Arrived in less than 24 hours. Amazing packaging. Comes with a license plate frame too. Pretty thick hoses. As for performance, I will have to update after install. Cosmetically they're a great improvement. Overall impressed with the product and Amazon

Very close fit... Had to fight with the pcv connections a lot but otherwise great.
