Quality product

This will be my second time purchasing this item from Rallysportdirect as I have over 20,000 miles on my old one. I'm not sure if it needed to be replaced but I decided to do it anyway. It's easy to install and the dyno from forums show gains from this specific Apexi dry filter. You will feel increased throttle response and a more distinct growling sound.

Great product!! A must for BRZ/FRS owners

Just ordered my replacement Apexi Panel Filter for my BRZ. This is a great product and I highly recommend it to make your BRZ/FRS feel better. In addition, I ordered this with a few other items from Rally Sport Direct and within less then 2 hours it was shipped and on the way to me. Finally, take the air box out when installing this, it is really easy to do.

I love this product for me a noticeable throttle response not sure if it added power but for me I noticed the throttle responds a little faster to my inputs.

Nice JDM upgrade

Fits perfectly in the stock airbox. Really nice JDM product. Highly recommended for someone wanting to keep the stock intake set-up but get a little more throttle response from a drop-in.

Excelent Cheap Upgrade

This is a quick (with some effort), excellent small upgrade to put on your ZN6 you can tell that there is a larger surface area on the outside of the filter because of the larger fins over stock. As soon as you drive away you can notice a difference but don't expect a night and day difference I have heard anything from 3-6hp gain on a Dyno but overall you can feel it too that the HP is more balanced over the RPM range.

  • Q: Durability  Ron O. 5 years ago


    As a maintenance free filter how long does it last?

    • A: This is going to vary based on the driving conditions the vehicle is exposed to. I would estimate anywhere from 5,000 to 20,000 miles.
