I bought this car used and the previous owner installed Nismo R-Tune Intakes. I recently purchased the HR stock intakes w/ K&N drop-ins from a friend but he doesn't have any of the bolts/other necessary hardware to install these.

Before anyone asks..I've spent around 2 weeks searching and making routine trips up to Nissan to try and find out what all is needed to revert my intakes back to stock. After spending ~$40 on random bolts that the Nissan Techs advised me to purchase..I returned everything for a complete refund. They obviously have no idea what i'm looking for. So hopefully I can get some help from the experts here

My question is, what all do I need? I noticed the intake ducts need to be bolted in, and there's a hole on the actual boxes to secure them down. So right off the bat, I know I need 4 bolts

 

can you take pictures of everything you have since my 08 350z is all stock atm and i might be able to help you

 

I numbered everything JIC, thanks I appreciate your help! I wish I knew the part numbers..ugh



Also - Do these go with the stock intakes? They look pretty beat up

 

How come you didn't want to keep the Nismo instakes? Those intakes are awesome!

 

I have no clue about the "what's this?" piece. but in #1 and 2 you just use those same plastic push-in clips that hold those trim panels in place around the battery and brake master cylinder compartments. For #5 and 6 use the same screws that hold in the top rear tab of each headlight. #3 and 4 are holes for clips on the wiring harnesses. Finally, those two metal brackets are for the front bumper's top edge, to connect the two outermost top plastic push-in clips to the next two next inner clips (feel under the top edge of the bumper). So, you probably only need 2 push-in clips and two bolts. Should be <$10. If your front bumper has all 6 clips in place along the top edge, you're probably OK there. But if not, you've got to pull the front bumper to bolt on the brackets, or you might even be OK without them.

 

I think they're nice, but i've been reading that the only two intakes worth leaving on the Z are the Injen CAI's and the stock airboxes because they actually make significant gains and don't rob the engine of any power.

If you take a look at my dyno, I made very weak numbers and the only explanation I can come up with for the poor results are elevation and/or these intakes.

What do you think?

Thank you for the help
