Review on ENA Set of 6 Ignition Coil Pack Compatible with Toyota Lexus Avalon Camry Highlander Sienna ES300 RX300 V6 1MZFE Engine Only Replacement for C1175 UF-267: Improved Performance and Reliable Engine Ignition Coils for Toyota and Lexus Vehicles by Andy Jolley

I have a '99 Lexus ES300 with 330,000 miles on it. He started to work poorly. I bought them back in April 2020 but I only recently (November 2020) installed them because I haven't ridden. After installing all 6 cars, the car started again. However, after about 2 weeks one of them failed. I replaced it with one of my old good ones and the machine works great again. but how long? They seem lighter and cheaper than the originals which lasted over 300,000 miles. At my local parts stores they are $300 for a set of 6 or $65 each when purchased separately.
