I got my Z-tube and K&N yesterday, so I woke up this morning ready for install on my 2003 Sedan. I have a question there is a metal mesh grill on the stock box, right behind the filter and where the z-tube will be connecting. Has anyone removed this mesh grill.

I took a video of what the car sounded stock and will take one after I make this mod, I can't wait. Thanks.

 

Can't help you with your question, but I look forward to hearing what it sounds like stock vs. after mods.

 

Haha...as a matter of fact. In about 10 mins or so I am going to install the z-tube and k&n myself. Check these links.

Sgt,

If I have everything setup later *hopefully*, I'll let you know. I get very picky on these little engine noise upgrades. Definitely let you know afterward.

 

Are you going to do a ECU reset?

 

Some people do and some don't. I probably won't.

 

Thanks, mikeee2. Appreciate it.

 

Thanks, but I did not see anyone talking about removing the mesh grill. Maybe someone knows, or tell me if you removed it. You will know what I am talking about when you take it all apart.

 

I saw the mesh that you are talking about and just left it in. It still sounds great with the K&N and Z tube.

 

Ok...just finished installing ztube and k&n. Alot easier than expected (especially for someone who is a dummy at little mods). The instructions were really good. For the K&N I didn't really have to follow the instructions. It was just unbuckle the 4 clips and the bolt. I didn't even notice where the MAF was and nothing was really in the way.

For Z-tube, it's easier to connect the pcv tube before attaching the rest of the tube. Also, the before and after, the tube are just as far far away from the AC line. I am not sure why people said it was rubbing it. I try wiggling the tube, it's stiff and has almost an inch of space between that and the ac line.

Will take it out for a spin soon. Exhausted from the heat 85+ outside.

 

No need to remove the metal mesh.

The concern with the tube rubbing against the AC line was more for the Injen intake tubes and not the Z-tube.

This mod combo really is a nice one.

Vrooommmmmmmmmmmmmm!

 

Ok I am back from a bit of driving. The Z-tube makes a bit more engine noise above I would say starting 3500 - 4000 rpm+. I can't tell if there is 1 or 2 additional horses if at all but the sound so far is pretty good. Need to drive in manumatic to hold it high on rpm and let it come back down otherwise in D it'll shift to higher gear and you can't hear much. Overall, it's not bad...

Ok...back to a little more driving...

 

I just finished my z-tube combo install. I did notice the PCV tube rubs against the side wall of the housing for the master cylinder and components. I assume it's ok as its probably this way on everyone’s G

 

Mikeee, any new impressions?

 

Hm...I never pay attention to what the pcv tube was sitting on or next to since no one mentioned that. Gotta check it tommorrow when I get a chance.
