Replacement Spark Plugs

[Torq2u]

OK. My question is about the right replacement plugs for my Alphard.

 

I have a 2005 2.4 with about 90k miles. It has Denso VK20 plugs fitted (can't see any other markings) which are the long-lasting version, but I don't know how long ago.

The Denso website still quotes IK20 or VK20 for my motor and I want to replace like-for-like (I understand that IK20s are not long-life). But it seems they have been superceded by a new number and VK20s are not easy to source.

 

Can anyone give a definite spec for either Denso or NGK plugs please? NGK numbering seems a nightmare as the cross-reference for VK20 leads to about a dozen different plugs!

 

Also, do new plugs come ready-gapped at 1.1mm?

 

Thank you 😘

Perhaps not a direct answer but if you put in Camry 2003 Petrol 2.4 into Eurocarparts it offers you DENSO and NGK options that should fit since it's the same engine AFAIK.

 

I should think they all come pre-gapped these days.

Amended model and year. I think the Avensis was a different engine.

Thank you Geralt. If they are indeed the same engine, I am pleased with those specifics (if not ECP's prices!).

Any sparks that fit the Camry will fit the Alphard. Same for the RX300 for the 3L. Bit of a pain to get at but once it's done great.
