Got the air filter system, paired it with a Bullydog GT Tuner. Install could not have been clearer, loved getting back to DIY I got my truck. Can't say too much about an increased MPG, but HP sure feels increased, and the truck seems much more responsive. Love it!

The instructions were not really clear. I had mislabeled parts and some things just didnt fit. I made them work. I have a noticeable bump in MPG & horespower as well.

I am a professional technician and have been in the business for over 40 years. I can't report anything on fuel mileage because I haven't gone through a full tank of fuel yet. There is a noticeable difference in throttle response, it's not as restrictive as it was before. I also noticed a mid-range difference which will help when pulling my trailer. The local Nissan dealer stated that the modification will not void the warranty if you follow the instructions properly.

Looks cool and sounds awesome, but the instructions are horrible! Overall, the product itself is worth the money but I wish it was preassemble since it came in a big box already. The instructions that were provided were mainly pictures only.

Great product! Increased hp and better mpg! It unleased the animal under the hood it's got a better sound now. I've also got an airaid throttle body spacer and bully dog tuner and its a totally different truck! Definitely worth the buy!

This review is simply my opinion. The install was very simple. I noticed a change in sound and throttle response. Doesn't really kick In until 3500 rpm. Once it does kick in you can tell a huge difference in sound and the way it pulls.
