Great.
Sienna 2004 CE. Original were NGK. Replaced first time at 160K with these ones. Work great. No problems where with old ones, just replaced them because was replacing leaking cover gaskets and did not want to do all work of removing top again in future. Hope they will last the same amount of time as NGK had been. While replacing bank 1 (next to firewall) replaced coils for three plugs. Coils were DENSO too. Used one that Amazon suggested.

Best Spark Plugs I ever used!
After 3 years of not doing a tune up on my car I finally decided to buy these spark plugs! After installation immediately felt my car running smooth! The spark plugs are pre gapped and easy to install! -Diesel Duke Jr.
