Anyone use Denso spark plugs (prt no. T20EPR-U)? I know the recommended part to use is the Bosch silver tip. Is there an advantage using the Bosch over the Denso?

They are absolute junk. Best plug to use at this point is the Autolite XP103. Much better than current Bosch offerings.

What problems did you have with Denso? I ran IT20 Iridiums from 2005 until this year when I switched to 1-step colder, no issue. Have ITV22s in my ecoboost motor.

Unfortunately Bosch is relying on their reputation, the parts now being made and labeled as Bosch are nowhere near the quality they once were. If you can find some old stock you would be OK but how do you know? If you have old Bosch plugs you can have them cleaned up and regapped and they should be fine.

I can't agree I ran a set of Denso plug in my snowmobile I had to put my old plugs back in to get home it would not rev high enough to engage the clutch after about 30 miles. ( it was an old yamaha triple 700cc )Originally Posted by Delorean Industries
