hi everyone, i reacently intalled new spark plug cable(from lexus), and some spark plugs, the brand is BOSCH platium +4. im not sure if that a good one for the sc400, or should i go back to denso or ngk.????????? i have a headache cos they are already installed.... please help me out and give me some sugestions...... thanks guys

 

Stay with NGK's or Denso's

+4's are over rated...and if you dont have enough "juice" (MSD or other) its pointless.

 

i got denso iridium very expansive but worth it because its a pain to do them.

 

thanks guys but i just want to use it normal, as a daily driver, are the bosch bad for the engine??? should i replace them???????? or keep them until summer.....

 

Bosch sparkplugs are absolute trash. You should avoid them in the future entirely. Go with NGK's or Densos, your best bet is to use OEM densos. You do not need to get iridiums, just get simple copper core/platinum tip plugs, they shouldn't cost most then $5 a plug.

 

should i change them now? or can i wait until summer???? i dunno wat to do...
but i will definitly go back to the oem denso, r the oem iridium? costs 14 bucks here in canada lexus dealer... will the bosch platium +4 damage my engine?????? thanks

 

are the bosch platium +4 dangerous for the sc400's engine??? T_T
