Great for performance sound.

Great sound and although there is no noticeable increase in power, the engine noise in the cabin has increased making it more pleasant.

Pros
  • High marks for support and durability from testers
Cons
  • Some bugs

Overpriced garbage fit replacement parts

It probably cost them $10 in materials. Very low quality. They won't even fit a grommet (rubber washer) in the tube hole so I had to spend too much time forcing them in. Get another brand.

Pros
  • Big fit for me
Cons
  • Faulty

Works well but needs better documentation

After about 2 weeks of using this on my Z I noticed an improvement in MPG. Another 1-2 mpg with that ethanol-damned gas. But what I really like is how much smoother the acceleration becomes. The engine is louder, but this is only noticeable when the gas supply is large. I am very happy with it. However, the documentation leaves a lot to be desired. First I also needed a torx (star) security screwdriver. Now I forgot what size but just in case you need it. The documentation doesn't say anything…

Pros
  • Robust construction
Cons
  • Updates available

Not bad, could be better.

I want to start this review by saying that if you live in California this is a great welcome for a low price. However; If you live in a state that doesn't have smog control, this probably isn't what you need. Pros: The air intake was easy to install and gave a noticeable increase in power and fuel economy. It has a great sound and the materials are durable and of high quality. It came with a CARB sticker and a serial number which I needed to be legal. The Bad: The reason I'm giving this 3 stars

Pros
  • This is amazing
Cons
  • Weight

Excellent kit, could do with some improvement

I bought this kit three years ago. This is my only engine mod. I wanted something that would pull my Z from 5000 rpm to the red line because it seems to "choke" with an inconsistent power curve. I chose K&N because I saw cheap lame kits and also kits with metal tubes. K&N uses a polymer tube to keep heat out and offers the best sound and performance in my opinion. When I put this piece on, I noticed a difference. Great sound, especially when shifting gears on the track. With every step on the…

Pros
  • Few competitors
Cons
  • not reliable
