Detailed Zip Tie Free Ram Air Mod Inside >>>>
**Updated to Mc Rat style**
Hey Guys, got around to doing the ziptie mod this morning on my car. Snapped some pics and put together a tutorial.
__________________________________________________
DOH!
Just came across this thread that McRat posted. I like the way he used the stock plastic tray to secure the filter a little better than the way I did it.

If someone can host it I have a MUCH more detailed version in WORD format. Please let me know if you can host. It is only 670KB.
Step1: Begin by removing the air filter
Step 2: Now remove the air filter lid by pulling the lid in the direction of the engine to release the rubber bushings holding the lid into place. Remove the lid & the lid straps. (Above)
Step 3: Now place the filter into the filter tray and re-install the filter. Be sure that the filter makes a good seal with the lower airbox assy.
Step 4: Put two zip ties together to make 1 LONG ziptie. Be sure to only slide the male end of the ziptie into the female end 3-4 clicks & trim the excess off of the male end of the tie.
Step 5: Wrap the long ziptie around the back of the lower air box assy and over the top of the lid tray and lid. Guide the ziptie to come out inside of the groove cut into the air filter tray. Repeat for the other side.
Step 6: Pull the ziptie tight and make sure that the filter is held securely in place.
You are done!

I will probably go the Halltech route in the spring when I have the time and money to get it tuned .

J-ROD posted up that the zip-tie mod is worth a dyno proven 12-15 rwhp.It was the first mod I did to my Z and you can't beat the price.Who needs a Vararam or Blackwing.

Actually you might want to look at this. I think it is a bit better way to do it...
I used the factory clamps. I simply removed the factory metal straps and replaced them with shorter one made from wire ties. This allows for consistent pressure to the filter frame.
Here Mc Rat's car. They just wrapped the ties around the box. I re-used the factory hardware to allow you to change the filter.
Hope this helps...

I don't know...
And yes, on my car it picked up 15RWHP and 11 lb/ft of Tq

I actually took VaraRam off from my car because I was having lot of issues with it like SES codes 0711 & 0174 and lean conditions, which was corrected with HP tuner. However, I did not see any gains on the track, if anything else, it was running bit slower than stock track time.

With bone stock, I ran 12.35@115.3, with VaraRam, I was running 12.45 - 12.55, so I decided to remove it and go with Zip Tie mod until return to the track to see if my suspicion was correct. I will do another tune and possibly another dyno before going back to the track to see if there are any changes.
Before with VaraRam CAI
After, Zip Tie mod
Yeah, VaraRam looks better but I just wasn't comfortable with it and Zip Tie mod is just a holdover until after the track runs and figure out what CAI I want to go with.
I've seen some posters stating that they gain something like 3 tenths and 2 to 3 mph, so I would have been happy with one tenth and 1 mph gains but I was going backwards. Now, I'm not saying VaraRam is POS, it just didn't work for me and I just wasn't happy with it's results or lack thereof so I am going back to the drawing board.
Here are couple disturbing pics of what was being accumlated in the radiator. I brushed and tapped the first of two radiators and all this junk fell out of it. :ack:

I have nothing against Blackwing filters from a construction standpoint Donaldson builds nice filters. My only issue with them is they are reported to cause issues on Z06's or any other car running an unscreened MAF, and the only way to solve that issue is to re-tune the car in addition to the filter.
I've looked at several of the "higher priced" intakes out there. In fact there is one on the H/C car that I drive. It materials and construction don't justify its cost IMHO. Plus, I have yet to see any real empirical evidence of any performance delta in an aftermarket air intake.
The new Callaway intake looks interesting however.
I have my car zip tied, and I don't consider it cheap looking, but, to each his own I guess....

I could only speak of vararam since that is what I had on my car. The cost to manufacture a vararam can't be no more than $50. There isn't much to it and cheap plastic material and filter doesn't justify 350+ dollars. Yeah, I know about cost of R&D since I work in R&D department but still, the entire parts which makes up vararam is cheaply constructed.

Looks like a good cheap way to get a better flow of air. I took my lid & cut away the bevels that were inside it to try and make more area for air flow. And put on a K&N stock replacement filter. I had thought of removing the whole lid & doing something like the zip tie mod before I had ever seen this posted here. But I was worried about water coming off the hood when it rained or washing the car getting the filter wet. But if other people have had no problems with doing this than I might go ahead & try it. It should work really well with the K&N that I have for the stock box. Wheres a good place to order a front hood seal? Just so I have some extra protection from water. My car is a daily driver for now.
Also I have thought since I have looked at this here about flipping the filter over and making an opening in the air shroud that goes to the radiator & letting it grab cool air from underneath. Or maybe even making a whole new shroud out of aluminum & incorporating a smaller scoop that directs some of the air from underneath directly into the filter. Sort of a ram-air from under the car maybe. That would be a little project.

Whats a good thing to use for the hood seal? Is it better to order one or just use some 3m self adhesive auto weather stripping? I seen some one ebay but it was just self adhesive weather stripping for like 12 dollars + 5 dollars shipping.

You can go to Lowes and buy door insulation, or window insulation. Either the foam, or the rubber. Or, buy a roll of generic weahter strip from the auto supply. All you are doing is keeping water from running right into the filter from the hood gap up front. You can do it for a couple of cents.

I decided to do the initial mod today. I decided to make mine with stainless steel welding rod bent to shape & I can still use my release clips to open & close it to clean the filter etc. I am about to go back out now & remove the air pump hose & plug the box where that hole is. I am going to use a breather filter on the air pump so it won’t be drawing air out of the intake box. I’m not sure if it really matters but I figured why not if I have the stuff handy. I got my hood seal & am going to put that on now also. Here are some pics I shot after I bent up the straps & put them on.
