As to "You should never gap an iridium plug", NGK's website states for Harley Davidson, these should be gapped at 0.40". I've found many websites stating that if re-gap is needed use care not to damage the electrode or the porcelain center. So, it's not that you should not re-gap, it's that you should be extremely careful. **Q: Are these 14mm threads?** A: Yes **Q: Do you get 1 or 2 spark plugs in this price** A: Pair / 2 plugs **Q: Is this 6r12, if so why does it not say so ?** A: Because these plugs are IX DCPR7EIX 99 TO 16 HARLEY-DAVIDSON ## Frequently Bought Together - NGK Iridium IX DCPR7EIX Spark Plugs Compatible with 1999-2016 Harley Davidson Twin Cam (Pair) - K&N Motorcycle Oil Filter: High Performance, Premium, Designed to be used with Synthetic or Conventional Oils: Fits Select Harely Davidson, Buell Motorcycles, KN-171C - K&N Motorcycle Oil Filter: High Performance, Premium, Designed to be used with Synthetic or Conventional Oils: Fits Select Harely Davidson Motorcycles, KN-171B --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/254497229-ngk-iridium-ix-dcpr7eix-spark-plugs-for-1999-2016-harley](https://www.desertcart.sk/products/254497229-ngk-iridium-ix-dcpr7eix-spark-plugs-for-1999-2016-harley) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-06-20*
