I know I cant be the only one that finds in insane that CAI's for our cars are $300 (if you get a steal on a used system) to $700. Has anyone had any luck making their own custom CAI? Piping really should only cost around $50-70 and the filters should be about $40-50 each. Also, are you throwing any codes because you're not attaching the sensor? If you've got pics or dimensions, post em!

 

It's cost/quality prohibitive. Other cars only need half the intake piping/filters ours do. Even your quote for a home made system is $170+. At that point, it makes sense to buy a used system that has some engineering behind it.

Edit: And I just realized this is a really old thread. Look what searching does for you, lol. At least you got the answer you've been waiting for all this time.

 

lol, I'm sure he's been waiting by his PC for 7 months, glad he can finally take a break

 

Waiting is a biotch

 

I'm still waiting

 

So I too did not want to spend nearly $400 + on an intake setup so i pieced one together. Used silicone hoses from siliconeintake.com (one 30 deg and one 13" or so long straight) and 90 deg aluminum pipe bends from cxracing. It took a little bit of cutting a tig welding (i did using my dad's tig) but in all wasn't that difficult. It's all 2.5" to mate up easily to maf sections i cut off a spare air boxes.

 

Almost forgot. The intake filters were from Z1 and are the same used on their kit. More pics.

 

 

Nice! No issues? Did you fashion a bracket to support the filters?

 

What was your total cost? I guess you'd have to have some spare airboxes laying around too.

 

I ran out of time to do that but it's definitely on the list to do this weekend. I'll post pics after it's done.

 

I got the airbox from a local guy who went ls swap and he was going to throw them away. So i lucked out and got them for free. The 90 deg aluminum pipes were $38 plus shipping. The silicone couplers (straight and 30 deg) $42 plus shipping. Hose clamps were sourced local for $10. The filters were $50 plus shipping. Total with shipping for me was $186.42. I bought everything over the course of 3 months then took an evening to make it all work. I did save myself a bit of money by welding the aluminum pipe myself, not all bad considering it was my first time with pipe and not the usual thick bracket I am use to TIG welding. I had the 'air baffle delete' silicone intake couplers already.

 

Good. Definitely something you don't want to overlook. That's the mistake I made and that's how I ended up with no AC for a year...

 

I paid 200 for new kn intake kit for my g37s through pepboys

 

I'm not even seeing any results for pepboys with the K&N part number 69-7078TS. Hell the cheapest i can find is ebay for $299. Also the K&N intake kit is more a 'short ram' pulling most of the air from the engine bay were the setup i made is similar to the Z1 and Admin tuned kits, pulling air from just behind the grill.
