Back in May at 40409miles, I developed a boost leak at the track. I did a pressure test and tracked it down to a busted F hose. The hose developed a split right at the elbow near the seam. I replaced it with a brand new Porsche F hose and today at the track the exact thing happened. The new hose developed a split in the exact same spot after a little more than 1600 miles. I don't think third time will be the charm and thus I'm looking at some after market options. Anyone have a suggestion for a more durable F hose? I don't want any crazy colors, just plain black and something that will be a good direct OEM fit. I plan on returning this busted one to the dealer as Porsche parts should have a 1 year warranty if I'm not mistaken. Thanks.

EVOMS? $135

Just asking ,,,Why would you have replaced the original one that cracked with another stock one when the after market ones are some much better and proven not to do that?,,Like the above one..

Holy F! I've had two Agency Power F's without issue. They looked similar to the evoms version listed above.

get a Forge one !

Samco F hose from AWE Tuning - basic, black, high quality silicone hose. About 70 bucks, from memory...

Just wondering how many of these parts house actually went out to different silicone hose mfg and had them custom mold an F-hose to hopefully sell ~100/year each for 70-140 each ?
I'd venture to guess Samco sells/mfg to everybody else.

That sucks. How much boost are you running?

The car has a RUF ecu which runs 1.2 bar. Most miles are track miles with very little street use thrown in. I just ordered a EVOMS silicone F hose which will ship out today. It seems all the aftermarket silicone F hoses are pretty much the same. I called 911 tuning, Forge among others and all I got was answering machines. Evoms actually picked up the phone, so 5 minutes and $90 later a new black silicone F hose is on it's way. As a side note, I've never had any issues with the stock OEM boost hoses which are actually a composite mesh encased in rubber. Zero leaks or issues with those. The stock F hose is the problem since it is just plain rubber molded from two halves. The seam is the weak point since that is normally where it splits. When I bought it I didn't realize that it was just plain rubber unlike the rest of the hoses. By then, I had everything taken apart so I put it in figuring that if the first hose lasted 40K miles and 10 years then this hose would too. Maybe I was drew the short straw.

i have a brand new forge and a used AP F-hose if you need one, PM me

Duct tape. 3$

I had the same thing happen last year at the track. It's a crappy design.

I replaced my with a Forge silicon one that seems very durable.

You probably know this, but in case others find their way here, dropping the engine 3" or so via loosening the motor mount bolts while supporting the engine with a floor jack makes this PITA job a lot easier. There is a DIY on lowering the engine here somewhere, but really very, very easy to do. Just be careful of the boost hoses coming from the intercoolers.

Thx, yep dropping the motor a few inches is the way to go. Done it many times. You'd have to have some tiny hands otherwise.
