Defender TD5 inlet manifold

Hi Everyone
I'm finally getting the courage up to change the core plugs in my 2000 TD5 Defender at the weekend as one of them is slightly weeping.

When I took the exhaust manifold off a couple of years ago it was an absolute nightmare with the studs snapping.

I know that I have to take off the oil cooler and then the dipstick (making sure I replace the o ring) just to get access to the manifold. My question is should I get the uprated studs by Wurth in anticipation of them snapping or do u think as it's the inlet the standard Land Rover ones will be ok (if they need replacing).

I also presume (probably wrongly) that the 3 core plugs hidden by the inlet manifold are all the same size and part number 37D2260L

Any help appreciated

Cheers

looks like they're the same

re' studs, always buy the best available to ensure no future snapping, tap out stud threads before re-fitting and copper slip on new studs.

I assume you mean exhaust and not inlet manifold?
If so are you aware on of the core plugs is threaded aluminium?

Hi mate - no I mean the inlet manifold. The core plugs are located on that side. These are the ones that tap in.

Yeah I think Ill go for the expensive studs just in case

Cheers
