Crossover pipes - what do I need


318touring

Recommended Posts

I've searched this forum, and used a couple of references posted here including the Design 911's crossover pipe kit.

In their kit they have included the 2 long hoses included, which is around 100 quid each, when added together made up around 40% the cost of the whole kit.

My question is, do I really need these 2 long rubber hoses as the failure points seem to be NOT at these hoses? 

What do you all think?  I have highlighted these hoses in Red for clarity in this picture taken from Design911's site.

Prett sure most people don't bother to replace those if there's no evidence of leaking/weeping at the joints. May of course depend on factors such as cost and whether you're paying for the work or doing it yourself.  NB if doing it yourself parts may well be cheaper from OPC or Spyder Performance. And have you seen the detailed video on YouTube?

My mechanic told me to leave well alone unless there were signs of leaking - generally its the front pipes that usually fail, not the long ones, but some prefer to swap out the whole lot if they are doing it themselves.

I had the front ones replaced on my previous car for around £400 all in - my current one had already had them done. Seems that they start to leak around 10-12 years old rather than mileage.

There are a few threads on here where people have DIY'd the job - some have been clever and found ways to avoid dropping the front sub-frame completely - its way past my level of car DIY :)

I'll most likely, definitely, outsourcing this to my local garage with detailed instructions.  Fortunately they dropped the subframe last year when replacing the left coffin arm.

I'd like to not spend the 200 quid for those pipes if not needed.

I'll check pricing around since I'm based in New Zealand.  I've found cars245 have consistently provided the best overall price including shipping.

Dropped the sub-frame to do a coffin arm?!?  That is a lot of unnecessary work unless the inboard bolt was corroded in place and they had to get it on the bench, even then normally possible to sort without getting the sub-frame off...

I noticed that you can get the 4 flexible hoses to the rads for about £80 - it seemed like a good idea to replace them almost as a maintenance item.  If you can get them changed before they corrode and damage the aluminium / plastic pipes you’ve saved a whole load of work.

 

Next time I’m under mine I’m going to have a look to see if I’m too late.

I had the lot refreshed on my 987.2.

If I was going to pay for it,  I'd save up, do the lot and get the parts from Porsche not a third party.

Just had all the front ones done on mine.  987.2 - 2011 car.  Done (mostly) under Porsche extended warranty - I paid for a few parts that were not ( or couldn’t easily be made to ) actually leaking.

Yup, corroded and they couldn't get it off.  This is not a Porsche specialised garage hence that would be the 1st time they work on a Boxster.  

My OPC wanted NZD404 approx. 200 quid to investigate my coolant leak ......

The parts from cars245 are all Porsche parts, as per this list.  It'll take them about a month to source the parts, but it's not urgent and the car can just sit in the garage.

Apparently the leak has been ongoing for a while, pretty wet down there.  Investigating whether there is anything needing attention by taking the liners and undertray off.

Could I ask where you got yours done please as that seems like a really good price & I’m not too far away from you (Southampton). My local indy quoted well over 1k ☹️
 

My car is 13yrs old this year so feel like I’m on borrowed time with them now!

 

Cheers

Now on to the type of coolant I should get?  Based on research, the Red one with Si-OAT will be suitable.  Something like this?  Keeping in mind that I live in NZ so different product availability.
