any experience with bosch +4 plugs

[canongate]

looking to replace plugs in 2006 lr3. Does anyone have any experience or knowledge of using Bosch +4 platinum plugs as opposed to the NGK iridium OE plugs?...thanks

I have used them since they came out in 2 different vehicle, averaging around 80,000 miles a set from them.

Stick with a NGK plugs, there is virtually nothing to gain and LR3 likes an original parts anyway, cheers...

My view original motor = original parts. When you start modifying to increase performance then you start looking at other upgrades. Besides the original plugs are good for 100k so why change to anything else especially something that lasts 20k less? I just use stock plugs in all my cars assuming that if it is good enough for the engineers at Land Rover and BMW it's good enough for me..
