Hard intake pipes for stock setup?

Morning!

just curious, other than the ones from CX Racing

https://www.cxracing.com/AI-13B-STOCK-FD

what other hard intake pipes are available for stock intakes?

i remember finding lots of options a few years back, but can’t seem to find them now.

thanks for the help, Tom

I think those are the only options that might fit the stock airbox. Back in that day, there were a bunch of cheap and expensive intake hard pipes but none of them actually fit between the lower hole in the airbox and the primary turbo inlet.
If you try them, please post results. If it actually fits the stock airbox, I might order a set also.

I'm curious of how these fit too. Seems kind of expensive, so I would hope they are perfect.

They are not, at least the primary turbo intake. The flange was a little warped, but it was within tolerance of the gasket

Here is a custom option.

I plan on changing out the clamps and painting the small black pipe.

It was roughly $460 in materials and $200 in labor.

I haven't looked in a long time but there used to be a number of inexpensive Chinesium hard pipes on ebay. The secondary turbo pipe generally fit well, the primary turbo was kind of a mess.

If you are going to cone filters or something the hard pipes are a lot easier to fit. Trying to go to an airbox can be a chore.

The HKS RS intake includes really nice large diameter pipes and is one of the few kits that bolts straight to the primary turbo eliminating the plastic turbo inlet. It's an expensive kit but really fits and flows well. Greddy has a really nice kit that's hard pipes and has a nice molded rubber coupler to go from the plastic turbo inlet to a hard pipe. There's also another Japanese tuner that has a hard pipe intake setup but I can't remember whose it is.

Bringing this thread back up,
did anyone ever end up buying the CX racing intake piping? I may buy them to replace my brittle oem rubber piping. Looking for any and all feedback. Thanks

Don't expect the primary turbo pipe to fit for crap, Secondary pipe fits OK.

How is your stock inlet piping brittle? I"ve never seen those pipes get bad or fail. Unless there was something crazy that happened like a fire or something.

May just want to find a good used set of stock hoses, they are a dime a dozen. The smaller hoses going to/from the blow off valves do get rock hard, I have a post about replacing those with silicone hose.

Here's an epic deal
https://www.ebay.com/itm/17118312680...cAAOxy4t1SlTHZ


seriously though, I bought some cheap ones from eBay (most likely CX Racing or whatever they were called before that) a decade ago and they work fine. It's crazy how a couple pipes cost 200 bucks these days. FEED ones cost 600 clams.

+1 to what Dale said.

I actually ordered a set of the chinesium ebay pipes 2 years ago. Bottom does not fit the stock airbox as expected.

It’s been years since I messed with it but I remember not being able to use that primary intake hard pipe with the stock coupler and straight silicone. Never thought of trying it at the time but wondering if a section of hump hose would have enough “give”, probably with a trim of the hard pipe, to make-up for the poor fitment. ??

Yes, you're right now that I think about it. It's been awhile, but I vaguely remember having to cut the pipe and find a larger silicone coupler.
