Yes, install them. I have a set too, sitting on a shelf just like you, and would like to know if they are worth installing. My 3.4 is naturally aspirated though. Good luck, wish I was close enough to help you.
Tough decision and I would love to own any one of them, but Double D, NateMob got my vote. I love the 3rd generation 4Runners and I love what he has done to her. Keep up the improvements and good luck to all.
Hello and Merry Christmas to all. I am a new member but a long time Toyota owner. I have a 97 Tacoma and 99 4Runner and previous owner of a 00 4Runner and 10 fj Cruiser. I am looking forward to new ideas and conversation.
