Which one should i get?

how do i install it?

Get whichever one you want, but I recommend the HKS SSQ. It is a pull type instead of a push type. Helps prevent leaks. Check out my website I have a few listed. If you get the RX-7 specific kit, you just take off the stock one and put the new on in the same spot.

I think stock ones are fine..



My choice is Tial.. They have the largest opening of all.

agreed. Stock is more than fine. If you must go with an aftermarket, get the Tial.

you should just use stock....



and if you want to have a louder bov, then just vent the bov to the atmosphere rather than the intake box, its louder than some aftermarket bovs out there

so just disconnect the inchor so diameter hose running from the bovs(are tan right)to the airbox

block off the hose running to the airbox

i have an apexi BOV and i dont want it anymore. i just got a BOV for the sound, no real need for an after market one. the apexi is too loud, i want one that is more high pitched, and more of a whistle. mine is more of a koosh. if you want the apexi one i have PM me. i just bought it about a month ago and the car got about a week of use with it installed. then i took it off and went back to stock. let me know man. https://www.nopistons.com/forums/pub...DIR#>/cool.png

Yes, if you like/want the sound, just disconnect the hose from the stock BOV and let it vent to atmosphere. Sounds as well or better than many aftermarkets, it's reliable, flows very well and it didn't cost you anything. Be sure to plug the open end of the hose or remove the hose at the airbox and then plug the airbox.

both unplugg both bovs

they're not both BOVs, but yes, you can disconnect both from the airbox.
