dmdvzla Posted April 29, 2013 Report Share Posted April 29, 2013 I have been doing some research about spark plugs, and I realized that most of you are using NGK's. My question is....has anyone ever tried BOSCH super plugs? If so, what was the experience like? I really want to know the cons and pros.... Thanks!

AUSSIEOLDIE Posted April 29, 2013 Report Share Posted April 29, 2013 Used them ages ago no problems. Do you realize that the multi earth super 4's or any brand of multi ground plug can only spark to 1 earth not to all 2/4 at the same time ?FWIW I use NGK Iridiums.

TexasQuest Posted April 29, 2013 Report Share Posted April 29, 2013 Don't try to experiment. Go with whats known best, NGK 7031's. 1 Link to comment Share on other sites More sharing options...
dmdvzla Posted April 30, 2013 Author Report Share Posted April 30, 2013 will some (kind or brand) spark plugs make the car run at a higher temperature? Link to comment Share on other sites More sharing options...
vbrad511 Posted April 30, 2013 Report Share Posted April 30, 2013 I've been running Bosch Platinums in my quest and my truck for years. Never had any issues, except when I switched back to Autolites in my truck. Thing ran like crap. Put a set of Platinum II's in it and all was well again.

patra_is_here Posted May 1, 2013 Report Share Posted May 1, 2013 Don't try to experiment. Go with whats known best, NGK 7031's. this seems to be the agreed upon best choice for nearly all the SQ's on this site. Link to comment Share on other sites More sharing options...
dmdvzla Posted May 1, 2013 Author Report Share Posted May 1, 2013 What I would like to know is if different spark plugs make a difference the performance temperature of these cars..or how the car performs?I know that there are "cold and hot spark plugs", but in my own humble experience; I think they only differ in the way the car idles when starting it in the morning...or when is cold. But do they make the car run at a higher temperature always? Link to comment Share on other sites More sharing options...

But do they make the car run at a higher temperature always? yes, the definitely make a difference on these cars. that being said, the optimal plug that's been found through hundreds of uses by dozens of users is the NGK7031 which is heat range 7 BUT, the temp range doesn't mean they MAKE the car run hotter/colder specifically.

Caliber308 Posted May 1, 2013 Report Share Posted May 1, 2013 (edited) It's the difference between a hotter, and colder spark given off. NGK cooler spark plugs have a higher number, hotter ones have a lower number. NGK BUR7EA-11 are the best choice in all around performance. Take it from someone who has tried them all: NGK 6,7 and 8s. The NGKBUR7EA-11 Spark Plugs performed the best. Bill Edited May 1, 2013 by Caliber308 Link to comment Share on other sites More sharing options...
patra_is_here Posted May 1, 2013 Report Share Posted May 1, 2013 BUR7EA-11 is the same as NGK7031, just different part number btw to the OP Link to comment Share on other sites More sharing options...
Caliber308 Posted May 1, 2013 Report Share Posted May 1, 2013 Heat range refers to the spark plugs ability to conduct heat away from the firing end. It must conduct the heat away in a even pattern to avoid becoming a source of pre-ignition, yet it must also operate hot enough to burn off conductive deposits that could cause misfiring.

Caliber308 Posted May 1, 2013 Report Share Posted May 1, 2013 BUR7EA-11 is the same as NGK7031, just different part number btw to the OP Same part number, same spark plug Using NGK 7031 just makes it easier for NGK. Less numbers and letters= less ink=less money spent by NGK Bill Link to comment Share on other sites More sharing options...
dmdvzla Posted May 2, 2013 Author Report Share Posted May 2, 2013 Thanks guys! my mechanic just put some BOSCH spark plugs on my car even though I told him to go with NGK. He said the BOSCH he used are the newest ones and best in his opinion....but I noticed my car runs a tad at a higher temperature compared to before.......

dmdvzla Posted May 2, 2013 Author Report Share Posted May 2, 2013 What's the difference between the NGK7031(BUR7ES-11) compared to the NGK's BPR7ES? Link to comment Share on other sites More sharing options...
patra_is_here Posted May 2, 2013 Report Share Posted May 2, 2013 projected insulator vs surface discharge type. basically the BPR has the electrode sorta out like the two on the lefthttp://3.bp.blogspot.com/-3cSRBARWyoY/ULMrk-8t8iI/AAAAAAAAAnQ/59851S850Ms/s1600/l%5B3%5D.jpg while the BUR is more similar to the right, but with even less exposed ceramic Link to comment Share on other sites More sharing options...
dmdvzla Posted May 2, 2013 Author Report Share Posted May 2, 2013 Thanks! so, which is best? Link to comment Share on other sites More sharing options...
patra_is_here Posted May 2, 2013 Report Share Posted May 2, 2013 the BUR's seem to the preferred plug for almost everyone on this site. Link to comment Share on other sites More sharing options...
BoostedBimmer Posted June 13, 2013 Report Share Posted June 13, 2013 My 88 Conquest manual says to use the NGK BPR7ES-11, so Im thinking that should be the correct design plug, and not the BUR7ES-11?? Link to comment Share on other sites More sharing options...
JohnnyWadd Posted June 14, 2013 Report Share Posted June 14, 2013 (edited) Best plug is the NGK 7031 like everyone said. I had some bosch platinums work great and some NGK iridiums too. http://www.starquestclub.com/forum/index.php?showtopic=136461&hl=7031&do=findComment&comment=1345328 Edited June 14, 2013 by JohnnyWadd Link to comment Share on other sites More sharing options...
