uhn medyo im looking for longer lastin ones na eh
..di naman yung mayado matagal..ksi i dont think its really necessary to change them every 5000 kms or 10000 kms.

pero okay na rin cguro stock..saan ba sure meron?

Keep the stock plugs and change every 10K-15K.

You can get better response/performance gains by advancing the timing a bit and switching to high octane IMO.

lahat ng plugs may self cleaning temp. ang denso iridium, eh copper core din. the difference is the tiny electrode which means that it needs a lower voltage for the spark to bridge the gap. application nito sa normal driving? maaring wala. mas maaapreciate mo ito kung turbo charged ka dahil mas dense ang laman ng cyllinder kapag naka turbo which makes it more difficult for the plug to spark given the same voltage.

Plus, mas matagal ang change interval ng mga exotic metal na plugs. pero, given the price, mas makakatipid ka pa din kung bumili ng normal na ngk at palitan ito every oil change.

diba may iba't iba't rating tong mga plugs na to? i think sa number.. 4 5 or 6.. number five yata pang slightly mod na car dba?

the numbers is heat range of the sparkplug.

so ano dapat? 4 ba yung para sa mga turbocharged or 6? malamang 5 na yung dapat gamitin ko diba?... and ano ulit yunf pag may letter "R" sa code? mas okay ba kunin yung may "R"? or pareho lng? hehe thanks!!

usually parehas lang yung may R sa side. 4,5 & 6 heat range plugs are pretty much for stock engines. you only go to 7-9 heat range if you have more serious mods on the engine like high compression, NOS or a turbo/super charger.

even casa will recommend changing plugs every oil change so i don't think going 10-15T kms will be advisable. remember, if you plugs are fouling na and not in the best condition, you gas milage and performance will suffer as well. replacing plugs at normal intervals is cheap and simple preventative maintenance for your engine!
