What made you choose this particular product?
Cost made me choose this product. I bought a no name cold air intake off eBay and replaced the cheap air filter with a K&N from Wal-Mart.
Is this your first time buying from this brand? Did you consider other brands?
I've used K&N in most of my vehicles. I've also used the Spectre filters from AutoZone which are a bit cheaper but aren't quite as good quality wise.
Was it easy to install? Any installation tips that will help others?
Being an inexpensive intake from eBay it requires some modification and adjustment. I need to pull it apart again for more modification so it'll fit better.
Once you've had a chance to use the product, did it meet your expectations?
Yes. It seems to help the car breath a little better. I'm sure a higher quality intake probably would've given me a bit more horse power and I may upgrade in the future but this will do for now.

Yes, was very easy to install. Installed it on my own.
Once you've had a chance to use the product, did it meet your expectations?
