Review on Denso 3478 Spark Plug by Richard Sallah

Exact replacement for stock fork. Good price and good performance. To update. I bought these forks on 8/23/16 and next weekend had about 110,000 miles on my 2013 Hyundai Sonata Limited 2.4 engine. I am now ordering another set for the same Sonata at 226,000 miles! I'm still getting 3,334mpg and running like a sewing machine, but maybe a new set of spark plugs will give me back the 37mpg I got in about 200,000 miles. Very happy with these candles and very happy with the Sonata.
