BOSCH 9614 OE Fine Wire Double Iridium Spark Plug - Single

I know there is some division on whether or not Bosch plugs work in Asian vehicles but I have Bosch plugs in my 2007 Nissan Altima 2.5 and my 2007 Honda CRV 2.4 and they perform great. I've read where some folks have an issue with sputtering and rough idle but that could be from fowled injectors, bad gas or any number of things. In my experience these plugs are terrific.

Swear by these spark plugs, they are ideal for people who put on extra wear and tear or just want to throw some plugs in and forget about it for 100k miles. I only use Bosch plugs in my Honda's and it gives me small but noticeable improvements in fuel economy, launch, and general good performance under bad conditions. Shipping could have been a little more delicate but can't beat the price, parts store wanted $36 for 4.

I gave these to my mechanic to install in my small 4 cylinder compact car. They replaced the original ones which had not been changed for 30,000 miles. While I cannot feel anything different while driving the car I am assured by my mechanic that these plugs are superior to what they replaced and they should last me many, many years. I will take him by his words.

Great value for money, fires really good but can't comment on the longevity yet cause I've only got about 2months on them.

Very pleased with the install, plugs worked as expected. Had a misfire where I thought the car was going to die on me, but diagnosed with code p0304. I knew it could've been several reasons for that code, but the cheapest route was to replace the plugs and sure enough, it took care of the misfire and the code.

The rolled threads make installing the plugs easy. (One of my old plugs was difficult to remove). No thread lock is needed, due to the thread design. These were installed on an engine with 260k miles. The down side is the sellers packaging. 3 of 4 boxes were opened, with the spark plugs rolling around in the plastic bag used during big brown truck delivery.

Started having problems with miss fires after one year. Changed out the spark plugs and now more problems. I expected the spark plugs to last longer than that.

Installed them on a Honda Civic, said they were pre-gapped.. Car ran like crap, checked the gab, way off.. After I adjusted the gap the car ran smooth.. lesson learned alway check the gab no matter what.. Takes a few minutes and you have the peace of mind that it’s the correct Gap!!

Very good spark plugs, recommended it!

I did not show for difference in the gas mileage or the performance but overall no worries I think it's good.

Cheap and good

Not reliable. Screwed up my engine with just a few km driven.
