I accept they might be good but things like that shout at me! I did put my ocd to one side and tried a set but I couldn’t get them to stop skipping and clunking on the direction change. It’s not a “tried it at school and didn’t like it” situation, I tried it at some expense and they ended up in the bin. I get the proper Denso ones from carparts4less and the next set is in my garage waiting. I’m very fussy so as soon as they streak or foam, they’re out.
