DensoIK20L IRIDIUM SPARK PLUG

These are a premium plug, and it's reflected in the price over it's similar competitors. However upon inspection, they reflect superior quality in their construction (and pointless but colorful packaging). Comparing them to the Autolite Platinum's they replaced, the nickel plating, the polished insulators, and precise electrodes and fine wire construction and it's no contest, these are better, hands down. I use Bosch in my other car and these are as nice if not nicer then those.As for how well they work? Great in our Honda. Quick install and torque, and it fired right up. Smooth idle and pulls nicely to redline. Combined with new Denso Oxygen/Fuel sensors and fuel economy is like new. Highly recommended!

I just had these installed in my 2010 civic, throttle response & acceleration are great through the whole RPM range. Great product, will most definitely inform all my honda club members.

Working great no problem and better performance

Great product

I Installed this set of 4 Iridium spark plugs in my 2004 Honda CR-V. The torque and throttle response improved, acceleration improved and the car felt much more responsive. I recommend those Spark Plugs for anyone needing to boost his car response and fuel economy.

Installed them on my Honda Fit Sport 2008 last weekend. So far so good.

Really great

They fit, they fire and the car runs. What more can I say?
