E3.56 E3 Premium Automotive Spark Plugs (4-PACK)

Ive been using these E3 plugs (multiple sets) for 10 years now, i change them out every 75k miles on my Dodge Neon and they've been working perfectly. No mid fires or knocking, engine purrs like a kitten despite what the OEM says about only using copper plugs with your engine i see no reason not to go iridium.I like these E3 plugs as they are force gaped perfectly, there is no guessing at what the gap should be or to manually bend them, and the gap wont change over time through use either.

I put a set of these in my ‘99 Ford F-150 Super Duty with a V-10. The plugs I took out were original spec plugs and the gaps were all over the place. I put in the E3 plugs at 141K. The truck now has 212K miles on it with NO problems at all. I found three different specs for which plug I should use. I finally went to the E3 site and looked up the spec there. I use these in everything from my lawn equipment to all 7 of my vehicles and they are fantastic.

My 2.4L Honda CR-V engine runs smoother with E3 spark plugs than with factory plugs. NE Cycle Shop shipped the plugs right away.

Amazing, these brought my car back to life, so powerful and no gapping needed ❤️2005 dodge neon
