samsplum 10 Posted February 5, 2020 I've read through a bunch of threads but haven't found an answer... I have personally always run Bosch W5DPO's in my modified G60 and they've been diamond, however they now cost an arm and a leg. Curious to see if anyone has personally run BOSCH W4DPO's? They're half the price and run in modified G40's apparently. Thanks in advance :) Quote Share this post Link to post Share on other sites
Brian1975 14 Posted February 8, 2020 These ngk iridium 4055 plugs appear to be recommended as an alternative to the Bosch W5DPO. Have no experience of them but they are considerably more affordable! https://www.maxrpm.de/NGK-Iridium-IX-plug-spark-for-series-G40-tuned-G60-190hp-Displaced-the-Bosch-W5DP0-0241247500-NGK-4055-BPR7EIX Quote Share this post Link to post Share on other sites
