Product Details

The Champion 312 Copper Plus spark plug (type L87YC) is designed specifically for small engines, delivering reliable ignition and consistent performance. This plug features a copper core electrode that provides superior conductivity and heat dissipation for dependable starting and smooth operation in lawn mowers, generators, snow blowers, and other small engine equipment.

Key Features:

  • Copper core electrode optimizes conductivity and extends plug life
  • Triple-coated shell provides excellent corrosion resistance in harsh conditions
  • Triple-seal assembly prevents combustion leakage for the strongest seal in the industry
  • Precision-rolled threads ensure proper fit and conform to OEM specifications
  • RFI suppression protects sensitive electronic components from interference
  • Engineered to resist overheating under heavy engine loads
  • Made in USA with Champion's quality standards

The L87YC design delivers proven performance across a wide range of small engine applications. The copper core construction ensures optimal heat transfer away from the firing tip, preventing pre-ignition and fouling while maintaining consistent spark energy throughout the plug's service life.

I bought an Exedy Organic Clutch at the best price I could find. Shipping was also prompt. Legit dealer, good business.

Great deals at unbeatable prices!

Product was as described, shipping was fast, and communication was excellent. Plus I saved $$. Thanks Autoplicity! I'll be a repeat buyer and referral source.

Found a Thule Vertex bike hitch on here for $50 cheaper than amazon. Extremely fast shipping. Definitely recommend purchasing from here.

Liked the amazon pay

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.

SO HAPPY! I have to admit, I was hesitant because I had never heard of autoplicity and there wasn't item a picture up for the Thule T2 rack I bought, but wow am I happy. Autopliicity had it for $100 less than other sites and the shipper was Amazon prime fast!!! Definitely a happy customer!!!!

I ordered a Thule 9002 Raceway Bike Carrier on Sunday, April 8 and received the product by Fedex on Wednesday, April 11 with just regular shipping. That is fast service. And the price was $43 cheaper than any other site on the internet (including shipping). I haven't had a chance to use the bike carrier yet but it appears to be new and as advertised with no issues as of this writing. I would definitely recommend this retailer for your next purchase.
