1995 Ls400 sparkplugs

[cilgwynbaby]

Hi,

I'm looking to replace my spark plugs, I had it converted to lpg about 4 years ago. I'm thinking of using Bosch irridium which I've seen on Opie Oils for £7.30 delivered. Any thoughts, advice on which ones to use will be appreciated.

I'd recommend you stick with the quality OEM plugs, Denso or NGK.

I’m with Colin. You mean £7.30 each..?

My OE was NGK and I replaced with Denso. I shopped around hard and got an ok price. Bear in mind they last a long time.

I went with NGK Laser Line, a line of products developed specifically for LPG.

Good decision or bad? I don't know because we've now sold our LPG-converted RX300, so all I can say is that they performed really well over the approximately 19,000 miles they covered before we sold the car.

I fitted the below on the basis that I was going to convert to LPG and they are supposed to run hotter. Two years on I've had no problems with them but as yet I've not installed the LPG kit - maybe soon.
