3.6 Inlet manifolds - genuine or Britpart

[Graeme]

Does anyone have a recommendation on replacement inlet manifolds for the 3.6 TDV8? The LR number hasn't ever been superseded indicating that LR haven't made any improvements to stop then from splitting whereas perhaps an after-market version might be an improvement. There appears to be at least 2 after-market versions with the Britpart one about half the cost of a genuine and another cheaper version listed by many ebay sellers.
My brother's MY08 3.6 has a split left manifold which is in the process of being removed.

Update: He's ordered the manifold and injector kits from his local LR dealer for not a lot more than genuine ex UK.

I gather by the term "splitting" that they are plastic Graeme?

Fair bit of work to get to. Seems to be a common issue, they either crack or the gaskets go hard.
Best of luck with it.

Yes they are plastic.

Thanks. I'll forward the link to my brother.

I note that according to Microcat 2012 the 4.4's manifold part numbers were superseded by the time the engine was fitted to the L405 but not again superseded. I'm hoping that my April 12 build L322 has the later manifolds as several minor improvements were made to the 4.4 in January 2012.

I would PM Dazza,he fixes these vehicles all day,for his opinion.

[Graeme]

He's already ordered genuine from a local LR dealer.

Unfortunately the manifolds aren't easy to swap out so risky fitting them.

L322?

[Graeme]

2012 was the last year of L322 production.

How much did he pay? My son has been quoted around $2000 each side so we are also looking at aftermarket. LR_TRADE_PARTS_UK state that their ones have been upgraded to prevent splitting and are about $650 for both delivered. They are probably sourced from China so the "upgrade" could be on the add only. If anyone has used the aftermarket ones please let me know how they went. At the end of the day the genuine don't seem much chop anyway.

I heard but don't recall the cost but $2000 sounds a lot more than what I have in mind. It was sourced from his local dealer. That the part numbers haven't changed indicates that the new probably one won't survive any better.

[KBarlow]

Has anyone any actual feedback on the aftermarket inlets? Anyone fitted them or compared quality. I am curious as I am about to embark on replacing at least the gaskets but would prefer to replace the intakes as well as a precaution. I tend to get "restricted performance" when towing the caravan which does not help.

[Graeme]

The originals will be quite brittle by now.

[haydent]

what error codes are you getting with the reduced performance ? how many kms ? it may just be some loose bolts or leaking gasket, do you have oil dripping from engine ?

[minesota]

The originals will be quite brittle by now.

my 5 cents...based on my experience
all parts are made now in China India or other exotic parts of the world with in many cases massive quality drop.
Even Land rover sourcing parts are not that good as use to be.
I got mine rocker covers from China for 360 AUD for both and so far so good.
my mechanic was impressed with quality and rubbers seals .

Also some parts LR decided to "superseded" not available anymore .

and Installation was a .... expensive exercise.... but you can do a lot of preventive maintenance like oil seals injectors seals , new upgrated turbo oil feeds Mamba.
From my experience many times aftermarket seals are better quality then "the original"

check ie Germax as they make very good quality parts for many brands.
