    Best plugs for Land Rover LR3

    Land Rover says 115,000 miles for these plugs, but I'd replace them long before that to keep performance and gas mileage up.

    Specified for Jaguar X308 Vandenplas 2000-2003 models with AJ27 engine)

    Recommended by NGK as the best spark plug for this model, these laser-welded, triple-gasket plugs have iridium center electrodes and platinum ground electrodes. Gap out-of-the-box was 0.044" (1.1mm). Adjusted by mechanic to original spec, 0.039" (1.0mm) -- although it seems Jaguar later increased the regular XJ8 spec for smooth idling to 0.052" (1.3mm). The NGK OEM plugs for the VDP are now 0.048", according to the dealer. I think these would have been perfect as-is at 0.044", but in any case they're working fine -- no knocking, and almost 20mpg around the city and 24mpg highway, and the gap increases with wear.
