Featuring nickel-plated rolled threads for corrosion resistance and factory pre-gapped for easy installation, these plugs ensure optimal performance and durability for modern gasoline engines, including Gasoline Direct Injection (GDI) systems. ## Description Bosch OE Fine Wire Double Iridium Spark Plugs are engineered to deliver both high performance and long life, representing advanced original equipment (OE) spark plug technology. The ultra-fine wire design and laser welded tapered ground electrode deliver optimum performance, while the iridium center electrode and iridium ground electrode inlay help it to go the distance. OE-matched spark position ensures compatibility with Gasoline Direct Injection (GDI) technology used in modern gas engines. Bosch OE Fine Wire 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. The Nickel-plated rolled threads provide maximum resistance to corrosion - ensuring the spark plug removes easily from the cylinder head without galling - and do not require anti-seize during installation - saving time. Bosch Double Iridium Spark Plugs meet or exceed manufacturer design requirements for OE fit, form, and function for modern gasoline engines. Unlock the performance in your engine with Bosch Double Iridium Spark Plugs. Review: I can feel a difference in the drive. - My old plugs were autolite xp iridiums and they had been in for a long time, finally getting about 1`00k miles and due for replacement. My Scion XB 2.4 still started, ran fine, and had no codes. My main concern was that the old plugs would get stuck in the cylinder head, despite using anti seize coating some years ago. The old Autolite XPs came out fine and new Bosch double iridiums were a perfect fit. The old plugs appeared fine, no damage, some central wire wear with a corresponding gap increase. Bosch double iridiums have the hard iridium surface on both the wire surface and the tip and should be more wear resistant than single iridium surface plugs where the center wire will wear off. On starting the engine a smooth idle was apparent but driving revealed that the engine was now more responsive at low rpms and pulled much more smoothly allowing me to shift my manual transmission at low rpm with improved torque. Additionally, on entering the highway I noted that there was no longer a surge when the rpm crossed 3000 rpm, it was smooth, linear and felt stronger. Additionally my factory mpg gauge shows a slight mpg increase. So far I am very happy with the investment in these plugs- 1. Chrome coating on the thread surface means I don't have to worry if I have to ever chance these plugs again, and no anti seize coating is needed. 2. The increase in torque, especially at lower rpms enables me to shift earlier and use less throttle. This increases gas mileage. The old plugs had what I estimate was a .004 inch increase in gap. A more robust spark at low rpms may increase the torque. Or perhaps the 30% advertised decreased voltage required to jump the spark gap allows a hotter spark which causes a better ignition. 3 Bosch guarantees these for 7 years. That's pretty darn good, although the Autolite plugs have a lifetime warranty. In seven years you ought to pull them anyway just to check them. Review: Actually real Bosch spark plugs / not cheap china trash - These were authentic Bosch plugs and was happy to see it wasn’t another china copy. They fit just rite and made a noticeable difference in my turbo lancer as I had auto lite double platinum with the fine tip in there b4 and wasn’t happy with those. ## Features - Bosch OE Fine Wire 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 maximum resistance to corrosion - ensuring the spark plugs unthread easily from the cylinder head without galling - and do not require anti-seize during installation - saving time - Bosch OE Fine Wire 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 including, but not limited to, the following (Note: engine affects fitment - verify specific fitment details with fit checker above): ACURA: 92-01 Integra, 91-95 Legend, 91-05 NSX; HONDA: 11-16 CR-Z; JAGUAR: 01 XJ8 - Compatible with (cont): JAGUAR: 98-01 XJR, 00-02 XKR; LEXUS: 94-06 ES300/330, 98-00 GS400, 01-07 GS430, 03-09 GX470, 10-12 HS250h, 90-94,97-00 LS400, 01-06 LS430, 98-07 LX470, 99-06 RX300/330, 06-08 RX400h, 92-94 SC300, 92-00 SC400, 02-10 SC430 - Compatible with (cont): LINCOLN: 00-06 LS; MERCEDES-BENZ: 02-04 C32, 05-07 C55, 03-06 CLK55, 00-04 SLK230, 02-04 SLK32, 06-11 SLK55; MITSUBISHI: 11-17 Lancer, 11-20 Outlander Sport; NISSAN: 99-01 Altima, 99-00 Frontier, 98-00 Pathfinder - Compatible with (cont): PONTIAC: 03-06,09-10 Vibe; SCION: 05-10 tC, 08-12 xB; SUBARU: 10-13 Legacy, 10-15 Outback; SUZUKI: 06-08 Grand Vitara, 04-11 Swift/Swift+, 04-06 Verona, 05-06 XL-7; TOYOTA: 03-09 4Runner, 95-04 Avalon, 92-11 Camry - Compatible with (cont): TOYOTA: 92-05 Celica, 05-06,09-10,12-13 Corolla, 01-10 Highlander, 98-07 Land Cruiser, 03-06,09-12 Matrix, 92-95 MR2, 96-08 RAV4, 05-12 Sequoia, 98-06 Sienna, 99-08 Solara, 93-98 Supra, 05-10 Tundra; VOLVO: 07-10 S80, 05-11 XC90 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0792LVCZW | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #57,004 in Automotive ( See Top 100 in Automotive ) #364 in Automotive Replacement Spark Plugs | | Brand | Bosch | | Brand Name | Bosch | | Compatible with Vehicle Type | Car, SUV, Truck | | Core Material | Iridium | | Customer Reviews | 4.6 out of 5 stars 709 Reviews | | Global Trade Identification Number | 00028851010382 | | Included Components | Spark Plugs | | Item Type Name | Spark Plugs | | Item Weight | 6.88 ounces | | Manufacturer | Bosch Automotive | | Manufacturer Part Number | 9603 | | Manufacturer Warranty Description | Limited | | Model Number | 9603 | | Thread Size | M30 | | Top Material Type | Iridium | | UPC | 028851010382 | | Unit Count | 1 Count | | Vehicle Service Type | Car, SUV, Truck | ## Product Details - **Brand:** Bosch - **Core Material:** Iridium - **Thread Size:** M30 - **Top Material Type:** Iridium - **Vehicle Service Type:** Car, SUV, Truck ## Images ![BOSCH 9603 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 1](https://m.media-amazon.com/images/I/71FZXJroy2L.jpg) ![BOSCH 9603 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 2](https://m.media-amazon.com/images/I/61GmL0w8STL.jpg) ![BOSCH 9603 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 3](https://m.media-amazon.com/images/I/61SR5jxEiPL.jpg) ![BOSCH 9603 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 4](https://m.media-amazon.com/images/I/51Q9udIwTTL.jpg) ![BOSCH 9603 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4 - Image 5](https://m.media-amazon.com/images/I/61xQszqJFIL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I can feel a difference in the drive. *by D***N on June 19, 2025* My old plugs were autolite xp iridiums and they had been in for a long time, finally getting about 1`00k miles and due for replacement.

They fit just rite and made a noticeable difference in my turbo lancer as I had auto lite double platinum with the fine tip in there b4 and wasn’t happy with those. ### ⭐⭐⭐⭐⭐ Better than platinum plugs *by G***. on June 23, 2025* Spark plug quality: I used to buy platinum plugs for their long life. A few years ago I switched to Iridium plugs and really like them. They typically cost less than platinum and seem to have even longer life. These are not re-gapable, so make sure they fit your vehicle. I like Bosch quality overall and when I checked the gaps, I found them to be perfect. ## Frequently Bought Together - BOSCH 9603 OE Fine Wire Double Iridium Spark Plug - Pack of 4 - FEL-PRO VS 50530 R Engine Valve Cover Gasket Set for Toyota Camry --- ## 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.ae/products/73330010-bosch-9603-oe-fine-wire-double-iridium-spark-plug-advanced](https://www.desertcart.ae/products/73330010-bosch-9603-oe-fine-wire-double-iridium-spark-plug-advanced) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-08-12*
