"This things sounds and looks great on my Xterra. I would say its a little on the pricy side for what you get, but I think this is the best CAI out there. It has a fully enclosed box, so no hot air from the engine compartment gets in. It looks really good, and for the most part is well made. The air filter is huge and looks nice sitting in the box. Now to the negatives. The directions leave something to be desired. If you dont know what your doing, you will get lost and not be able to get it installed correctly. They should be more detailed. Also the part were my air temp sensor plugs into the box, is not very secure and looks like it could fall out if you go over a big bump, leaving me to add a rubber o-ring on the inside to secure it better. Overall great item, matched with a new muffler and your good to go!" —Jonathan L from Reno, NV bought a Volant Cold Air Intakes for a 2003 Nissan Xterra, 3.3L V6.
