2011 Honda CR-Z w/ a Blitz SUS power intake.Got this filter to replace the Blitz one that came in the kit of the same size. The K&N feels much better made. They're not inexpensive, but you buy it once, clean it when its dirty- done.

Added this to my AEM intake on my turbo optima in the hopes the the sound would deepen a bit. That didn’t happen but the filter itself worked perfectly , as I needed more room under the hood.

Installed it in my 2010 Legacy Wagon GT. Removed the original airbox and installed a 6 in flange to accommodate this filter - perfect! looking forward to a long service life from this K&N product

As expected with K&N filters, this one is built to last. This filter replaced my spectra filter that broke at the neck. Very happy with this purchase.
