Ls400 Small Service Advice

[Psychosaffa]

i have a 95 ls400 that i want to give a service.

i have a genuine toyota air, fuel and oil filter, but am not sure what spark plugs to get. i saw some NGK iridium ones on the bay, for £60 odd quid, and some Bosch super 4 ones for £42. i dont mind spending the money, but are the iridium ones worth the extra £20?

also what is the suggested oil to use? and how much would i need?

thanks in advance

Hi Manuel ,personally I would only use the NGK or Denso iridium plugs . As for oil I use Toyota 5w-30w fully synth £22.99p delivered for 5litres .

iridium ones are better to use, cannot recall all the tech details, worth the extra

Blimey,I can't get over,what we pay for iridium spark plugs these days,it's not a gripe,I look after my LS400, maintenance,and cosmetics apart,but when I think of paying a £1.00,for 4 Champion N5's, for my old Ford Cortina,...............

10 years ago I paid trade price of @ £96 for a set of 8 NKG plugs, they have certainly come down in price ( amazing, not much else has ) and the latest 4 NGK plugs on my partners Mazda cost all of £12 I think !
