Exup Man 0 Posted February 11, 2006 Just been to get some new plugs from GSF. They list the W6DP0 plug for my G60 on the web but sell the new WR6DP0. Whats the difference? Quote Share this post Link to post Share on other sites
Supercharged 2 Posted February 11, 2006 R = Resistor but not sure what difference that makes... Quote Share this post Link to post Share on other sites
exturbo2003 0 Posted February 14, 2006 R = Resistor but not sure what difference that makes... helps stop the ignition hf interfering with electrical things including your ecu and peoples tellies Quote Share this post Link to post Share on other sites

Supercharged 2 Posted February 14, 2006 I know that but does it affect price or performance and why don't the ones VAG recommend have the R? Quote Share this post Link to post Share on other sites
bcstudent 0 Posted February 14, 2006 Being a resistor I suppose it limits the ignition current. Effects (I'm guessing) would likely be more consistent running and a longer spark-plug life at the expense of a negligible power loss and price increase. I have no idea why the recommended plugs aren't R-rated. Perhaps R-rated plugs weren't available back in the days of Corrado production and VW never updated the records to keep with the times. GSF supplied me with R-rated plugs for my 1.8 16v last week and I can honestly say I've noticed no performance difference. Seeing as I've got such little performance to start with, even minimal losses would be evident! Quote Share this post Link to post Share on other sites
RW1 0 Posted February 14, 2006 why don't the ones VAG recommend have the R? Cos the resistance is already in the leads at 5Kohms or there abouts. Not needed on the VW............. . Quote Share this post Link to post Share on other sites
Exup Man 0 Posted February 14, 2006 Thanks for the info. It was more a question regarding the 3 ground electrodes versus 1. It did have champion plugs in that have seen better days. The WR6DP0 plugs have made a difference. Quote Share this post Link to post Share on other sites

Not needed on the VW............. . thats ok if people have genuine leads as most dont. bcstudent, your plugs should be resister type. also when they first started using platnium plugs you couldnt get resister types hence the high resistence in the ht leads Quote Share this post Link to post Share on other sites
