NGK Platinum Sparkplug

May Mazda 323 Sedan 93 model is using NGK BKR5E sprkplug, can I use the NGK Platinum Sparkplug? In a shop they offer me to use the Platinum NGK, as they claimed it is better than the stock. Tnx..

better as in mas matagal ang buhay nya.... but performance wise, better stick with the stock ones (yung nickel)....

nako...had bad experiences with platinums lalo na sa JAPANESE cars. may mga customers kami nag nagreklamo kasi ang bilis masira ng plugs nilang platinum at umuusok kotse nila.

i myself experienced this.

pero may mga benz owners nagsabi sakin na ok naman daw ang platinums sa kanila.

better stick with stock.

so far saken, no problem using those platinums (bosch, NGK) for more than 5 years na, lalo na yung NGK G-Power Platinum,. used more than 2 years (w/ religious cleaning), then used on another vehicle, still performing, no fouling etc., ganda parin ng performance,.. just my 5 cents and my experience.

so kung platinum gamit mo, mas matagal bago palitan,

pero you have to clean it?

how do u clean plugs?

Using the platinum equivalents of your stock plugs should be fine... i noticed the poor feedbacks usually comes from those using, for example, Bosch plat plugs on a Jap engine that uses either NGK or Denso.

stupid question: ano difference ng BKR5E and BKR6E ngk plugs? tagal ko na suspect kasi na mali yung plugs na install ng shell gas station sa car ko because ever since they serviced it the mileage went down. last thursday, wala ako ginagawa and on my last day in pinas (went back here in indonesia last friday) i decided to pull out the plugs. ayun BKR5E naka-install, manual says BKR6E. could this be the cause of my low mileage? 34T km on the odo pa lang so far and the first 30T km the mileage was purty good, until i had it serviced.

higher heat range sya... meaning, the plugs are colder...

Colder plugs are usually used whenever you do some major engine upgrades (like higher compression ratio or going forced inducted).

On stock engine, better stick with the manufacturer specified heat range... Higher heat range plugs are more prone to fouling (if higher is used compared to recommended, although better if you always stay on higher revs). On the other hand, going for lower heat range promotes detonation...

Cold plugs = high heat range = disperses heat much faster = usually higher number sa part number ng plugs
Hot plugs = lower heat range = disperses heat slower

(ex. for NGK BKR7E = 7 is the heat range number, so it has higher heat range compared to BKR5E)

malaki na ba ang kaibahan ng bkr5e sa bkr6e ?

malaki rin.... if you would compare them side by side, mas malalim yung part ng 5E na nakapasok sa loob ng cylinder... so, mas mainit nga sya.... yung 6E, mas malaki part nyang nakakapit sa cylinder head, so madaling ma-disperse ang heat.

Back to topic: Basta, I don't see any good selling points for the Platinum plugs which is P150 isa, and Iridium plugs which is P550 isa.... P70 lang yung stock Nickel...

mas matagal ang buhay ng Platinum and Iridium (meron pa nga palang Silver, but uncommon and sobrang mahal), but if you would try to compute for their lifetime over their price, talo pa rin sa cost effectivity eh...

I'd have new fresh plugs na lang lagi na Nickel keysa cleaned(every tune up) Platinum or Iridium - kahit na every 5000Kms ok lang, di masakit sa bulsa ang Nickel. Platinum and Iridium plugs also have lower conductivity compared to Nickel, kaya maganda pa rin ang Nickel...
