Product Details

The Autolite AR4153 is a high-performance racing spark plug engineered for modified and competition engines that demand reliable ignition under extreme conditions. Built with a copper core electrode and non-resistor design, this plug is purpose-built for the track where maximum ignition energy and durability are essential.

Key Features:

  • Yttrium-enhanced alloy ground electrode — delivers up to 8% reduction in side wire temperature, enabling colder heat ranges that support performance modifications and help prevent pre-ignition
  • Cut-back ground electrode design — exposes the spark for improved ignitability and faster flame kernel growth, promoting quicker, more complete combustion
  • Anti-corrosive nickel-plated shell — resists rust and corrosion better than standard black oxide finishes for long-lasting durability
  • High alumina multi-rib ceramic insulator — provides superior thermal conductivity and electrical insulation while preventing flash-over
  • Non-resistor construction — maximizes ignition energy transfer, preferred in dedicated racing applications

Specifications:

  • Thread Size: 12mm
  • Spark Plug Reach: 0.753 in. (19.13mm)
  • Seat Type: Gasket (Flat)
  • Gap: 0.025 in.
  • Heat Range: Autolite 11
  • Wrench Size: 5/8 in.
  • Electrode Core Material: Copper
  • Electrode Tip Material: Nickel
  • Insulator Type: Projected / Ceramic
  • Terminal Type: Non-removable Nut
  • Resistor: No

That was quick, I just hope I get the CORRECT part as hassle free and in the time I paid for.

Good so far with a lot details about parts. very good prices

Very fast, clear and secure order placement but there was a problem with the mails. My shipping address was different than my billing address. On the confirmation mail the names were changed while your website showed it correct. It was a little confusing.

A+++ service and upadates.

Checking out through Amazon made me feel at ease when shopping through a new site, that was an awesome an unexpected convenience and I've searched the web for this part and hadn't purchased because I couldn't trust them. Amazon checkout is awesome!

Love shopping here, I always find what I need.

Great!!

Ordered some fluid coolers for a project, great price, easy website, FAST shipping!

So far so good

Shopping was quick and painless. Also the prices are very competitive.
