For the price i don't think anything would beat them. They are one step colder than the factory once from Mitsubishi, and they cost way cheaper than the stock once. I used to pay less for these, but it seems desertcart increased the price. Never had issues with them, and they would last a long period of time. I have them changed every month or two, since i run my car on race fuel ( VP Q16 ), and the car makes nearly 700 to the tires. I used to run IKH22 when my car was making ~400 HP and those lasted forever, and never had to change them for months. It says on the box not to even think of gapping them as all iridium manufacturers say, but i do gap them to 0.018" and that works perfectly for my power level. Review: Your car will LOVE these! - Just put them in yesterday. These things made the car feel a lot smoother in idle and power. These are a great product replacement upgrade. Recommended torque specs is on the box, which is great. -2015 Volkswagen GTI ## Features - 0.4 mm iridium center electrode: world's smallest diameter that maximizes firing potential - U-groove and taper cut ground electrode: provides faster spark flame growth and lessens heat quenching - DENSO patented 360 degree laser welding process: ensuring exceptional quality bond and structural strength with the iridium center electrode ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000M6WPXM | | Best Sellers Rank | #299,684 in Automotive ( See Top 100 in Automotive ) #66 in Automotive Performance Spark Plugs #5,457 in Automotive Ignition Parts | | Brand | Denso | | Brand Name | Denso | | Compatible with Vehicle Type | Car, Truck | | Core Material | Iridium | | Customer Reviews | 4.2 out of 5 stars 108 Reviews | | Gap Size | 0.8 Millimeters | | Global Trade Identification Number | 00042511053465 | | Included Components | Spark Plug | | Item Type Name | Spark Plug | | Item Weight | 0.05 Kilograms | | Manufacturer | Denso | | Manufacturer Part Number | IKH24 | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Thread Size | 1.25mm | | Top Material Type | Nickel | | UPC | 042511053465 | | Unit Count | 1 Count | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** Denso - **Core Material:** Iridium - **Thread Size:** 1.25mm - **Top Material Type:** Nickel - **Vehicle Service Type:** Car, Truck ## Images ![5346 Spark Plug - Image 1](https://m.media-amazon.com/images/I/71j0LjNNt3L.jpg) ## Questions & Answers **Q: Is this a 12 mm or 14 mm spark plug I need this information for the gapping tool** A: Neither!! You need to gap them properly yourself, so get a “gapping tool” if you plan to use them properly. They take a little work, but they are OUTSTANDING! I have them in my Stage 2 GTI that makes damn near 350hp from a 4 cylinder... They do the job! Just use them with care! #NotForTheLevelOneTech **Q: are these pre gapped at.44?** A: Can't remember the gap mine came at but as a general rule you should never trust the factory gapping. Get the electrode bender and the shim set for about 4 dollars to check/set the gap yourself. Do not! Use a gapping disc on these plugs, you will damage the iridium tip. **Q: Does anyone know the difference between the ikh24 and the ik24?** A: From what I can tell they are completely different plugs. **Q: Does this fit an 01 Tacoma ?** A: Yes, but I wouldn't recommend it. This spark plug has a very tight gap and isn't optimized for your Tacoma. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Iridium FTW *by Y***I on November 11, 2010* I use the IKH24 on my 2006 Mitsubishi Lancer Evolution IX MR.

I gapped them according to APR's suggestion of .024” +/- .002”. It runs great and haven't had any problems. Side note on changing the plugs, be patient and have some WD40 handy. The ignition coil doesn't like to come off easy. ## Frequently Bought Together - Denso 5346 Spark Plug - PQY Universal Spark Plug Gap Tool with 32 Blades Steel Feeler Gauge for Most 10mm 12mm 14mm 16mm Spark Plugs Red - LEXIVON 5/8" Swivel Magnetic Spark Plug Socket, 3/8" Drive x 10" Total Length | Enhanced Magnetic Design with Thin Wall Socket, Cr-v Steel (LX-122) --- ## 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.com.br/products/14172161-5346-spark-plug](https://www.desertcart.com.br/products/14172161-5346-spark-plug) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-06*
