Product Details

The DENSO 3442 is an Iridium Long-Life spark plug engineered to meet the strictest OEM performance, durability, and emissions standards. DENSO's iridium plugs are manufactured using the same processes and materials found in original equipment applications across a wide range of domestic and import vehicles.

Key Features:

  • Iridium center electrode — ultra-fine 0.4mm tip promotes a more complete burn and consistent ignition performance
  • OE-quality construction — manufactured to the same specifications as original equipment spark plugs
  • Long service life — iridium's superior hardness and melting point far exceed standard copper and platinum plugs
  • Improved fuel efficiency — precise spark delivery supports optimal combustion and reduced fuel consumption
  • Reduced misfires — stable spark kernel improves cold starts and idle quality
  • Emissions compliant — designed to help maintain factory emissions performance throughout the plug's service life

DENSO is one of the world's largest OEM spark plug suppliers, and the 3442 Iridium Long-Life plug reflects that expertise. It is a direct-fit replacement that installs easily without modification, restoring ignition system performance to factory levels.

GREAT!!

Couldn't find the optional insert for the product , pan 20 . Only found that on scribblers catalog . Should be listed as an option on your page .

Did not install because no torque specs on product. Too difficult to have to do twice because of install failure. Was emergency situation. Had to just risk 1300 mi. Valve damage.

Fast and easy

Quick & easy, so far...

Yes I receive my order

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

great prices

Great prices and FAST shipping!! Definitely will buy products here again!

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.

Easy and fast. Order arrived very fast. Thanks.
