Bosch Automotive 9614 - Single OE Fine Wire Double Iridium Spark Plug Review

The product comes pre assembled and is very easy to install. There was installation instructions on the box that said do not use anti-seizure and do not reuse. I ordered 4 of these spark plugs for my 2008 Honda Fit but received 1 wrong spark plug. Returning the wrong spark plug was relatively easy, so I'm very happy with the purchase.

I gave them to my mechanic to fit my small 4 cylinder compact car. They replaced the original ones that hadn't been changed in 30,000 miles. While I don't feel anything different while driving, my mechanic assured me these spark plugs are better than the ones they replaced and should last for many, many years. I will catch him according to his words.

I know there is some controversy as to whether Bosch plugs will work in Asian cars, but I have Bosch plugs in my 2007 Nissan Altima 2.5 and 2007 Honda CRV 2.4 . and perform great. I've read that some people have problems with splatter and rough idle, but it could be from clogged injectors, bad gas, or something else. In my experience these forks are amazing.

Swear by these spark plugs, they're perfect for people who put in a lot of wear or just want to put in a few spark plugs and forget about it for 100,000 miles. I only use Bosch spark plugs in my Honda and it gives me small but noticeable improvements in fuel economy, starting and overall good performance in poor conditions. at 4.
