hey wasup..... i was wondering..... when is a good time interval to replace spark plugs.. and which do you guys recommend?? i heard the bosch platinum +4 are the best... anyone know why??? any feedback would be appreciated.. thanks a lot!

 

Every 30,000 miles. Don't worry about getting Split Fires or Bosch platinums. I got the Denso Iridiums and they are just fine.

 

well getting the stock replacements is what's 'best' for the car. and if you check your manual, it should say what milages to change the plugs. i would go by that. they must know what they're talking about in there....they built it.

 

100,000 to 110,000 with platinum spark plugs.

30,000 with the copper.

 

thanks for everyones feedback!!
