Purrs like a kitten, now. Does not require any anti-seize lube during installation, and specifically says so in the instructions; it's nice to not have to buy that. All of the old plugs were Bosch Iridium and came out easily. I decided to upgrade to the Double Iridium model, to "help" the older engine, approaching 140,000 miles. Drives nicely and idles more smoothly than it has in a long time. A little bit expensive compared to the Champions, but they should have a much longer service life, which is important for an older car that I will most likely be the one performing the repairs on. Review: Upgrade to Iridium - I installed a set of 16 of these spark plugs in my Chrysler 300C and have observed a noticeable improvement in the smoothness of the engine at idle. I believe there is about a 2 mpg improvement in gas mileage as well, but only at highway speeds. I have somewhat of a heavy foot in town, so my MPG has not changed there. These plugs are very high quality, and may last the life of my car. I highly recommend them. ## Features - Bosch Double Iridium Spark Plugs feature both an iridium firing pin and an iridium ground electrode inlay that offer higher performance and 4X longer life compared to standard copper spark plugs - 360-degree laser welded ultra-fine wire iridium firing pin provides better ignitability - reducing voltage requirements up to 24% - and enhanced durability - Nickel-plated rolled threads provide superior resistance to corrosion and do not require anti-seize - making installation quick and easy - Bosch Double Iridium spark plugs are pre-gapped at the factory and ready to install right out of the box - gap adjustment prior to installation not required - Meets or exceeds manufacturer design requirements for OE fit, form, and function for modern gasoline engines - including Gasoline Direct Injection (GDI) engines - Compatible with select vehicles (Note: engine affects fitment - verify specific fitment details with desertcart confirmed fit fit checker above): CHRYSLER: 2005-08 300, 2007-08 Aspen, 2001-10 PT Cruiser, 2001-06 Sebring, 2001-03 Voyager - Compatible with (continued): DODGE: 2001-07 Caravan, 2006-08 Charger, 2004-08 Durango, 2003 Grand Caravan, 2005-08 Magnum, 2003-05 Neon, 2003-08 Ram 1500, 2003-08 Ram 2500, 2003-08 Ram 3500, 2001-06 Stratus; JEEP: 2006-08 Commander - Compatible with (continued): JEEP: 2005-08 Grand Cherokee, 2002-05 Liberty, 2003-06 TJ, 2003-06 Wrangler ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00515NK9C | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #2,365,836 in Automotive ( See Top 100 in Automotive ) #10,853 in Automotive Replacement Spark Plugs | | Brand | Bosch | | Core Material | Iridium | | Customer Reviews | 3.8 3.8 out of 5 stars (47) | | Date First Available | June 1, 2011 | | Exterior | Machined | | Global Trade Identification Number | 00028851013727 | | Item Weight | 0.8 ounces | | Item model number | 9654_1 | | Manufacturer | Bosch Automotive | | Manufacturer Part Number | 9654 | | Model | Spark Plug | | OEM Part Number | 9654 | | Product Dimensions | 4.2 x 4.1 x 1 inches | | Thread Size | 14mm | | Top Material Type | Nickel | | UPC | 028851013727 | | Vehicle Service Type | UTV | ## Product Details - **Brand:** Bosch - **Core Material:** Iridium - **Thread Size:** 14mm - **Top Material Type:** Nickel - **Vehicle Service Type:** UTV ## Images ![BOSCH 9654 OE Fine Wire Double Iridium Spark Plug - Single - Image 1](https://m.media-amazon.com/images/I/7146NFBC01L.jpg) ![BOSCH 9654 OE Fine Wire Double Iridium Spark Plug - Single - Image 2](https://m.media-amazon.com/images/I/71FZXJroy2L.jpg) ## Questions & Answers **Q: Do they work efficiently on 2005 5.7 v8 hemi engines made by chrysler? 05 hemi v8s are known to have champion copper plus spark plugs proclivity. t.y.** A: Hi Edward: Bosch (9654) work for the 2005 Chrysler 5.7 V8 hemi engine. They are fine wire double Iridium lasting up to 4x longer than the copper plugs. Iridium and platinum are not as efficient or conductive as copper, and both of these metals are prone to overheating. As long as they do not overheat, they do last longer than copper spark plugs. Although copper has the shortest lifespan, it is generally considered the best material for a central electrode because of its excellent conductivity. **Q: What is the difference between the Bosch 9654 and 9664?** A: One is prolly hotter/cooler than the other and or is more/less protruding into the combustion chamber than the other. Best advice: follow the recommendations on the application charts. **Q: Will these work in a 03 Dodge Ram with a 5.7L hemi** A: Yes they will work on your 03 Dodge Ram 5.7L Hemi. I personally would stick with the original spark plug manufacturer that your truck came with (Champion). They also have Iridium plugs (9403 Champion Iridium). **Q: is $5.00 for one plug or a pack? How many in a pack?** A: 1 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice, consistently good plugs for my '06 JGC! *by M***M on April 22, 2018* Went easily into my '06 Grand Cherokee with Hemi (16 total plugs).

They do their job nothing special ... *by D***E on November 24, 2016* They're spark plugs. They do their job nothing special. No increase in HP no increase in MPG. Stop trying to push your voodoo on others. Only difference will probably be longevity due to the iridium. ## Frequently Bought Together - BOSCH 9654 OE Fine Wire Double Iridium Spark Plug - Single - BOSCH 9654 OE Fine Wire Double Iridium Spark Plug - Pack of 4 --- ## 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.pt/products/1741462-bosch-9654-oe-fine-wire-double-iridium-spark-plug-single](https://www.desertcart.pt/products/1741462-bosch-9654-oe-fine-wire-double-iridium-spark-plug-single) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
