I've used ngk in the past many times and never had a problem with them. The only thing that you should really know is that like all other plug manufacturers they are pre set to a gap of their choosing and not necessarily the correct gap for your particular engine. These arrived gapped at sixty thousands so I had to adjust the gap down to fifty thousands for my car. ### ⭐⭐⭐⭐⭐ Don't wait to change your plugs *by on Reviewed in the United States June 28, 2026* Great spark plugs love it if it not acdelco it NGK make my 97 chevy ride like a new truck will buy again good price will buy again thanks ## Frequently Bought Together - NGK 3951 Spark Plugs TR55 (8 Pack) - ENA Set of 8 Curved Boot Ignition Coil Pack Compatible with Ford Lincoln Mercury 4.6L 5.4L V8 Replacement for DG508 C1454 C1417 FD503 1L2U12029AA I2LU-12A388-AA C1417 DG473 DG481 DG491 --- ## 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.sn/products/45306202-ngk-3951-spark-plugs-tr55-8-pack-replaces-sp400-sp446](https://www.desertcart.sn/products/45306202-ngk-3951-spark-plugs-tr55-8-pack-replaces-sp400-sp446) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-24*
