Hello,

I have heard a few people talk about making a Ram Air or Forced Air Induction system to replace the Horrible Nissan Air Box, does anyhow have any pictures of these after they have been installed or can someone lay out exact instructions? I can pretty much figure out the part about buying the filter and using either a PVC pipe or something like, and buying a K&N Air Filter, and putting it roughly in the same area as were the airbox used to be, but how about the RAM AIR portion? How is the air forced into the filter? What is Scooping the air per say? If anyone has any picture I would be most greatfull if you would email them to me.

<b>RE: Ram Air</b>

Motorsport has a nice ram air replacement for the air box. It has a chrome finish and K & N filter (cone shape). Sorry no pictures but look in there catalog.

Steve's is really good-Thanks-

When you listen to a regular air filtered Z you can't hear anything unusual..When you listen to the Steve-o-matic filtration system you can hear the air sucking in like a frikkin tornado. Steve uses black PVC and I use 3" exaust pipe with the K&N RU-0900 filter.. Thanks Steve..

Thanks guys, my opinion inside

I gotta say that I haven't put my car on the dyno yet, I have one available and will get to it sometime next month and let you all know what the screaming cheetah is putting down to the wheels. IMO unrestricting the intake by using a larger diameter pipe and a K&N filter is one of the best and least expensive ways to gain an estimated 10-15HP that I can think of. Replace the exhaust system too and your Z will perform Very Noticeably better. This is not just a guess, It revs much quicker and does not strain at all like stock Z's. Do this Intake Mod and you will not be sorry...

Do what I did - and the cost is great: FREE!!

Take off the top off of the stock air box - the piece with the trumpet that points to the passenger side. With a die grinder or cutting wheel, cut the top off completely, about 1" from the edge of the lid, so you still get an air-tight fit around the filter. This exposes more than 90% of the filter surface directly to the intake air stream. I noticed an immediate improvement in throttle response, and you get that great "vvwwoosh!!" sucking sound...
