Default Replace all Vacuum hoses?

Soo i have a 05 WRX and was wondering if it was gonna be worth replacing the vacuum hoses?
I want to get blue hoses to change the black hoses and to also prevent any leaks i might have.. Ive noticed that FASTWRX sells a "Vibrant Silicone Vacuum Hose Kit" for a pretty decent price to me and includes all of the following;

5 ft. of 1/8" (3.2mm) I.D. hose
10 ft. of 5/32" (3.75mm) I.D. hose
4 ft. of 3/16" (4.5mm) I.D. hose
4 ft. of 1/4" (6mm) I.D. hose
2 ft. of 3/8" (10mm) I.D. vacuum hose

Do you think this will be everything i need beside coolant lines and such? I already have the hoses for the TMIC and yet to replace my turbo inlet which i will if this kit includes almost every line. Thanks for your input!

When i put in my new short block in my 02 i did... All of them were stiff and brittle, and many broke during disassembly. Turbo inlet is a great idea too if you're taking the manifold off. The side that goes on the turbo gets pretty fragile with age.

I got all my hoses from https://www.siliconehose.com, including the heater hose. It all cost under 60 with shipping, and i did order more than necessary so i would have extra. I still have the receipt if you want to know the sizes.

Heres how mine looked right after i dropped the motor back in:

Silicone hoses can save you a ton of headaches down the road...I've been going through mine and can't tell you how many hoses are brittle and cracked. Those all eventually lead to vacuum leaks.

Plus they're super heat resistant. On my last car I ran one right over the hot side of the turbo without any issues. (Not resting on it, obviously)

Thanks,

Heres what i bought:

----------------------------
Vacuum hose:
13mm x 8 feet
6mm x 6 feet
4mm x 8 feet

Heater Hose:
0.31" x 8 Feet

Total = $59 with shipping
----------------------------

If my memory is right you could probably get by with just 6 feet of each diameter vacuum hose. I think the only ones i didn't get there was, the larger one on the upper coolant reservoir and a large one where the pcv system connects to the block (pictured below).

You absolutly should post up a detailed DIY sizes and all


I have the Vibrant hose kit (havent installed) but the hoses used for the "breather tubes/black aluminum tubes running infront of the IC" it doesent seem like it supplies you with enough length to do the 3 hoses.


One question I do have is since the outer diameter is bigger on the silicone hoses....should I be using "worm gears" to tighten them down rather than zip ties?

Yes you should. The hose that goes to the the overflow tank isn't pressurized though and doesn't require a clamp. I just put zip ties on for good measure.

When I changed all of my hoses to Silicone I noticed slightly better throttle response and improved gas milage. This is the kit I ordered and it's great.

I bought the Vibrant hose kit, but the problem I am going to have is knowing which oem vac line is which size

5 ft. of 1/8" (3.2mm) I.D. hose
10 ft. of 5/32" (3.75mm) I.D. hose
4 ft. of 3/16" (4.5mm) I.D. hose
4 ft. of 1/4" (6mm) I.D. hose
2 ft. of 3/8" (10mm) I.D. vacuum hose

I haven't done it yet due to not having time. But from ive been reading online its best to buy all the hoses separate. Just because people been sauing that the kit gives us less of amount hoses to make it work complete as a plug and play.

If you guys want ill go out and buy all of the hoses I might need and do a how to since my car is currently apart at this moment.
