Hey guys, im going to put new spark plugs in the Rx (somehow some POS bosch iridium ones got in there) and I'm 50% sure my mpg's have suffered because of them! anyways I saw that denso made long life part #sk20r11 and the performance version listed as Ik20's...so I was wondering which one would yall prefer. Thanks!

 

 

A big NO to Bosch! Also do not get the performance iridiums as they do not last nearly as long and you will almost certainly not tell the diff in performance. Go with the Denso's or NGK equivalent. I used to be married to Denso but now prefer NGK. Denso says on their packaging that their plugs may be made by a Denso approved supplier instead of Denso. I do not go for that.

 

+2...no to Bosch. I prefer the NGK iridiums. BKR6eix-11

 

Ok great!!! Thanks tons guy's!!! Now to that SOB mechanic that put in those bosch plugs 6 months ago!! About to go have it out with him cause I paid for denso! I want my 100$ back!

 

When the German's start sourcing the engines for these, then i will consider Bosch parts.

 

Tell me about it...my experience with bosch is terrible...damn those Germans lol
