darrencnz 10 Report post Posted July 7, 2016 Hey guys I want to replace my spark plugs in my M52 engine and before i just go and purchase whatever the factory spec ones are, does anyone have any advice on something better? Is there another plug that is more suitable for our gas we use here or any other reason to get a different type of plug than the factory spec one? Thanks Quote Share this post Link to post Share on other sites
Mr Vapour 76 Report post Posted July 7, 2016 i cant answer tou question but can tell you the best place to buy NGK. I worked there in the past. by far the best price you will find, they import direct from JApan. STA 09 2561120 1 Quote Share this post Link to post Share on other sites
darrencnz 10 Report post Posted July 7, 2016 Handy, my girlfriend is japanese, might just get them from there myself... It's one of those topics that can get a range of answers but i just thought there might be someone who can advise a better performing plug for NZ fuel/conditions...

Olaf 3317 Report post Posted July 7, 2016 +1 - NGK. My M54 uses Iridium. Consider your coils as well; over time these degrade. Sure, they're producing a spark... Quote Share this post Link to post Share on other sites
darrencnz 10 Report post Posted July 7, 2016 Thanks guys One of you bought up an interesting point... My ECU has been modified for some of the changes to the engine... I might get i touch with the guy who did that and see what he says...I never even thought about that until someone brought it up.. Cheers Quote Share this post Link to post Share on other sites
NZ00Z3 187 Report post Posted July 7, 2016 (edited) I run NGK BKR6EQUP in my M52TU and M54 engines. Get them for about $20 each through trademe, Trader does not always have them listed but they come up every couple of weeks. Been told that Bosh plugs have a habit of coming loose over time in the M52 and M54 engines. Have not used Bosh plugs at all so can't confirm this from my own experience.
