Hi,

As a newbie non-technical owner, looking for recommended parts brand; also, OEM or aftermarket? Doing my first tune up and have no idea which brands to use, especially spark plugs. Would truly appreciate your wisdom on this. Thx.

 

For spark plugs, the V12 likes NGK ones, BR7EF. There is no need to get the fancy ones, the engine seems to like the plain ones better.

I use a mix of aftermarket an OEM parts, depends on what it is. Coils don't seem to matter too much, wires I use Lucas or Denso. For cap and rotor I managed to get a genuine Marelli, not sure if those are still available.

 

what do u think of denso sparks?

 

"It depends"

Most of us go aftermarket but you have to be careful what you're buying these days. Aftermarket quality varies a lot on some items. Best to post here, case-by-case, and hear what others have to say. On certain items, relatively few, genuine Jaguar OEM is favored.

Cheers

I've not used them. NGK is what Jaguar recommends.

 

The NGK spark plugs are cheap and good. No idea in trying anything else

 

NGK basically only does plugs and they are what belong in the engine.

Basically every manufacturer grabs into a deep parts bucket and builds using what he can get hold of. So nearly everything has an OEM supplier who will sell without the Jaguar stamp.

For example:
- Balljoints: Lemförder
- Brakes: ATE
- Filters: Mahle/Mann
- Spark plugs: NGK
- Marelli parts: Marelli or NGK (when available)
- Shocks: Boge
- ...

After like being around for 40 years, most licensed parts have been 'off license' so aftermarket sales are possible (like with the ball joints). So no Jaguar only parts required.

Just keep in mind, that good OEM parts aren't super cheap. Üro was never OEM. But does do some (!) good parts... But suspension parts aren't quite up high in their quality thoughts.

 

I think one of the biggest things is where you buy from, rather than what you buy. There are so many fake parts out there - yes, even fake spark plugs. Any manufacturer's genuine part is going to be preferable to you thinking you're buying premium and getting a fake!

 

Agfree with all that has been said.

Only thing I will add is, if you have an original Marelli cap and rotor and they are in good condition keep them, aftermarkets are not as good a quality. I have both and the aftermarket cap I have has flat aluminium posts, original Marelli has round brass.

 

hi, I couldnt find a Marelli so I got Intermotor made in Italy. The current Marelli has 77k miles. Do you think I should keep Marelli if looks ok?

thanks for advice.
