Stillen Hi-flow intake and Ztube Install

[aiya]

You reuse the bolts from the OEM intake. The four holes in the back of the aluminum velocity stack (inside the filter) are where the OEM MAF sensor tube bolts on. :thumbup:

I forgot if I was able to reuse mine or not.

Is it an easy install? I looked up a instal and it talked about cutting off a piece off to install. I might just go downstairs and give it a try before going to the gym.

Super easy for the FX kit, but I think soonster is right about that z-tube being a 350z version. No biggie, just replace the OEM air box with the Stillen. Its a 10min job.

When I had installed my Ztube, the LINE has to be facing upward. If installed correctly, the accordion tube should be aligned as straight. There are also ARROW indicators on the parts if you look carefully.

I definitely did reuse mine.

longer bolts are required since he has the stillen heatshield. JWT didnt offer, correct?

 

[aiya]

No heat shield on my JWT.

So I tried to install the it and it was a no go since the bolts are not long enough. I will go buy them maybe today or tommorow and try to install it later on this weekend.

 

[soonster]

you might want to pick up 4 tension washers too

 

[ocal21]

Will do that thanks, what about the washers that are on right now will those not work?

 

[soonster]

u can certainly try. stillen package them and should look like these:

I bought my intake direct from Stillen and it didn't come with bolts or lock washers. I think i got screwed! :p

 

[ocal21]

Hey on the stillen website where they have the parts for the intake they show a round silver metal item. What is that and where does it go?

 

[soonster]

which silver metal item?

here's a PDF from stillen site: http://www.stillen.com/product_files/402835~inst.pdf

Cone Filter sleeves into the "silver metal item" > HEATSHIELD > MAF TUBE > FLEX JOINT > Z-Tube > FLEX JOINT > Throttle Body.

That's the one with the bolt holes in your picture. Its a velocity stack that fits inside the cone filter.

 

[ocal21]

Oh so that's why there's the thing I tighten the cone. I was wondering if I got screwed when I bought it used. But I def need to buy the long bolts to tighten the cone.

 

[soonster]

if Tim can squeeze the oem bolts, guess you can probably do the same.

Just my 2 cents since this was my first mod and I could be doing things wrong:
I have done the same installation on mine FX35 last Christmas and noticed the followings:
1. Stillen included 4 longer bolts but didn't mentioned what those were for in the installation manual. I was stupid and naive (so I wasn't take tic tac) since that was the first mod and didn't realize those 4 bolts were to replace the OEM bolts since they are not long enough. After trying really hard on using the 4 OEM bolts (tried an hour scratching my head...and sweating all over in my <30F garage) , I gave up and went to Homedepot to get some longer bolts....then I realized those bolts were actually offered by Stillen. So if you received those bolts, use them. The OEM bolts might be barely enough if it is hotter (just joking....they are too short in my opinion) and it was <30F that day. Go get longer bolts from any hardware stores.
2. My rivets were broken and just hang there without any real function. But so far after maybe 5k miles and I haven't had any problem.
3, There is another bolt that fastens the Power Duct to the side of the engine bay. It wasn't an easy fit for me. I can barely get it fastened while keep the rivets in place (that's why the rivets are just hanging there now without function).So far this bolt seems to keep everything in place.
4. It took me some twist to get the Z-tube in and the vacuum hoses attached. It was a tight fit and the whole setup wasn't totally straight (pretty much like the pic shown in the previous post).
5. I did notice a more aggressive sound but can't tell much power gain through my Butt dyno. I did feel (maybe just physiological) a stronger pull in mid to high rpm after installed the Mrev2 + 5/16 spacer.
Hope this help
