bryant2482 Posted June 3, 2013 Report Share Posted June 3, 2013 like the title says, are they worth the money and do they really make a difference in performance? Quote Link to comment
metalmonkey47 Posted June 3, 2013 Report Share Posted June 3, 2013 No. Waste of money. Stick with NGK 1 Quote Link to comment
DanielC Posted June 3, 2013 Report Share Posted June 3, 2013 I thought they only worked with fuel line magnets, to align the fuel molecules, and you used a "tornado" air vortex generator in the air intake. AS SEEN ON TV! Quote Link to comment
datzenmike Posted June 3, 2013 Report Share Posted June 3, 2013 Do they display testimonials by people that have tried them? Placebo effect. If you think it will improve performance/gas mileage/last longer you become biased and your observations pick out the good and throw away the bad. There is a tendency to also believe that the more you spend on something the better it has to be. If anyone got better mileage it was probably from subconsciously driving slower and more carefully. Anyone can get 10% or more better fuel mileage. Quote Link to comment
TFM1066 Posted June 3, 2013 Report Share Posted June 3, 2013 the only thing that can boost more spark is a better coil or more voltage to the coil, sparkplugs are the slave in the system. Quote Link to comment
datzenmike Posted June 3, 2013 Report Share Posted June 3, 2013 A 'bigger' coil will only help if more voltage is actually needed as in added compression, turbo or SC. Quote Link to comment
Stupid_fast Posted June 3, 2013 Report Share Posted June 3, 2013 NGK BPR6ES. If there's nothing wrong with the plugs, don't bother using anything else. Though BPR5EY's seem to run better in my hopped up L20b. Can mess with heat ranges if you have issues with the plugs. Quote Link to comment
nismo dr Posted June 3, 2013 Report Share Posted June 3, 2013 no. I wouldn't even put those in my lawnmower Quote Link to comment
bryant2482 Posted June 3, 2013 Author Report Share Posted June 3, 2013 ok so while were talking about spark plugs but whats recomended to go in a KA24E? Quote Link to comment

DaBlist Posted June 3, 2013 Report Share Posted June 3, 2013 E3 SPARK PLUGS Can't believe they still exist. Their marketing has changed a lot over the years from blatant lies into implied lies. A spark plug can not split a single electric spike into multiple sparks, can't happen. If an engine runs better with them it's because there was a problem with the other plugs. OOPS, maybe I was thinking of Splitfires Quote Link to comment
Z-train Posted June 3, 2013 Report Share Posted June 3, 2013 Splitfires revisted.As bad a Flow Bastards and other automotive handjobs Quote Link to comment
GreaseMonky Posted June 4, 2013 Report Share Posted June 4, 2013 What about changing heat ranges if your running a lot of compression? Quote Link to comment
izzo Posted June 4, 2013 Report Share Posted June 4, 2013 Those are the best spark plugs you can get man :devil: use them along with your fram oil filter. Quote Link to comment
Stupid_fast Posted June 4, 2013 Report Share Posted June 4, 2013 What about changing heat ranges if your running a lot of compression? Read the plugs after a hard run ... if they're getting fouled or otherwise incorrectly cleaned/colored play with the heat ranges to find the best for your motor... As I said, I ran a hotter plug in my hopped up L20b due to fouling plugs, it ran a bit better after. Quote Link to comment
banzai510(hainz) Posted June 6, 2013 Report Share Posted June 6, 2013 I havennt bought a set of spark plug in over 10years. I pull them out of L motor heads I getr free and maybe sand blast them. but NGKs and Nippondensos are the ones to get. The threads are correct also. autolites have a slightly weid threads and will be hard to get out so dont use them. Im sure the spark is fine but just what I experienced. Quote Link to comment
datsunaholic Posted June 6, 2013 Report Share Posted June 6, 2013 I had the opposite problem with autolites- damn things kept falling out. Champions, those got stuck. I've also had nothing but bad things to say about Bosch Platinums. Several cars had 'em in them when I got them and they always fouled. NGK. BPR6EY if you prefer a "groovy" plug. BPR6ES if you want to go standard. NipponDenso plugs are OK, but they're a Honda plug. Quote Link to comment
harlow426@msn.com Posted November 19, 2013 Report Share Posted November 19, 2013 From my experience(air cooled vw's, old Triumph m/c, kart racing engines) I think the ngks and nippondenso plugs are overpriced & offer zero performance improvement. The original "BOSCH SUPER" or standard Autolite is the only way to go in my book(3rd choice Champion). Clean your threads in the head with q-tips and carb/choke...then smear a bit of anti-sieze on the threads b-4 installing. Sandblasting used plugs is risky....what if some of the blasting media makes it inside of the motor? If u can find N.O.S. "Splitfire" plugs buy them(made by Autolite)....they almost never foul(fuel/oil/heat) and in some applications they actually made more power on the dyno(high compression, wild cam, methanol, header). If u flood a NGK when running alky good luck getting it to fire again. I find running one heat range hotter in #1 and #4 helps low end fuel burn/throttle response(Chrysler reccomends this in the Mopar performance book on L6 225 slant sixes). I also prefer solid copper washers on the plug verses the steel crush washers supplied w/ plugs...be sure to index electrode "gap" towards intake valve/piston. U may need to use a flat surface w/ abrasive paper 2 trim the thickness of washers down 2 achieve this. Gold irridium, platinum, and the like do not hold up to higher temps(lean)......standard Bosch, Autolites R TOUGHER. Quote Link to comment
Z-train Posted November 19, 2013 Report Share Posted November 19, 2013 From my experience(air cooled vw's, old Triumph m/c, kart racing engines) This is why you don't know that NGK's are really the ONLY choice for Datsuns. Splitfires? They are an "automotive handjob" bigger than Flow Bastards. Quote Link to comment
datzenmike Posted November 19, 2013 Report Share Posted November 19, 2013 air cooled vw's, old Triumph m/c, kart racing engines.... maybe even probably but it doesn't translate over to Nissan. And what works in a race car...... Quote Link to comment

We sold a ton of those POS's and most of them came back. European = Bosch Japanese = NGK Ford = Autolite Chevy = Delco Quote Link to comment
harlow426@msn.com Posted November 20, 2013 Report Share Posted November 20, 2013 Maybe I wasn't clear above.... I was just giving a well rounded suggestion based on my experiences. Yes I have a wide background(other than just Datsuns) but I've tested/tried it all on my Z24s,z22s,l20b. I just cannot justify spending more $$ on NGKs. If u watch the ads/rebates autolites are almost always cheaper. If I thought NGKs were better or had an added benefit I'd buy them. 2 each his own I guess. One other thing on the spark plug subject.....if u have a bad head/gasket(water oil in combust chamb), bad ring/ vlv guid/etc a set of Champion L87YC plugs will run the longest b-4 getting fouled and will "self clear" more quickly than anything else Ive found....HOT plug.

datzenmike Posted November 21, 2013 Report Share Posted November 21, 2013 You could do the same with a hotter NGK plug. The Champion/Autolite or whatever are not an exact match. They may be close but will be slightly hotter or colder than the factory recommended NGK. I find that Champion (no I didn't run them in a Datsun) tighten wrist tight and yet you need a breaker bar to loosen them later. Quote Link to comment
datsunaholic Posted November 21, 2013 Report Share Posted November 21, 2013 We used to use Autolites in our 1710 cubic inch V12 Allisons. These run Avgas, and are supercharged and make around 2000 HP @ 4000 RPM. Big engines. We have to run the coldest plugs around, or they melt. But the Autolites have a horrid tendency to foul and rust. Even after sitting less than a week between runs, we've found the plugs rusty, black, and extremely hard to clean off. The rust happens because the plugs are overheating, and they are the coldest plug available for that thread and reach. By sheer coincidence, one engine had 12 Autolites and 12 "Accel" brand plugs in it. The Accels upon further inspection had "ND" cast onto the body, which told us they were just rebranded NipponDenso plugs. So, I went to Rockauto and bought a set of NDs, which while slightly more expensive (0.20 a plug) than the Autolites were far cheaper (by over a dollar) than the price we'd been paying at NAPA. A full year later and close to 12 heats of running, the plugs are clean, no rust, and not fouled. This is for plugs with the same equivalent heat range. We are NEVER going back to the Autolites. I've had similar problems with autolites in Datsuns. Besides backing out (in 2 different engines), they come out fouled. NGKs run clean and I've yet to have one fail. Like Mike, I've experienced the self-tightening Champions. Snapped one off in a head, it was quite the chore getting it back out. I have no problem with Champions in my Lawnmower, though. It all comes down to application. Quote Link to comment
