Review: Bosch Exclusive -- DOUBLE IRIDIUM !! - The Bosch #9605 is a DOUBLE IRIDIUM design, which uses an Iridium coating on BOTH electrodes. Another desertcart customer recommended installing Iridium spark plugs in my V-8 engine, so I did a ton of research on the subject in order to get the best plugs for the least money -- and here's what I found out: The Bosch plug is the only DOUBLE-IRIDIUM design that's currently available -- and the only plug that has both of the Iridium-tipped electrodes laser-welded to the plug . What the illustration doesn't show is that both the center electrode and the ground electrode have iridium surfaces --, which should translate to a superior plug with even longer life than other brands of iridium spark plugs. The Bosch 9605 comes pre-gapped at 1.3 mm (.052) and does not require re-gapping for most applications. Most factory-gapped plugs are famously inaccurate, but a double-check showed the 9605s to be spot-on in every case. These plugs are marked * Made in Germany * on the box, with the proper gap and tightening torque, also. There is NO anti-seize necessary, as the plug is plated to avoid corrosion while allowing proper torque readings. Use of PermaTex Item # 22058 Dielectric Tune-Up Grease (available from desertcart) on the inside of the plug boots prevents boot damage and stops high-voltage terminal corrosion. Use a thin film of dielectric grease on battery posts and terminals to stop corrosion and loss of battery voltage to the electrical system. UPDATE: May 22, 2020 -- After 40,000 miles of use, the Iridium plugs are still providing excellent performance and fuel mileage. Engine starts instantly, idles smoothly, and runs strong.
Review: Great plugs for my little hotrod. Does increase pickup of acceleration. - I use these in my ford ranger V6 3.0 . They give noticeable increase in power. The engine sounds like it is solid and has more pickup when changing gears or driving at high speeds. They do the trick. Gas mileage is ok and i use non-ethanol gas since it gives me better mpg. Its a rebuilt 95 and purrs down the expressway. Im lucky to have a great mechanic who works for himself and i can depend on when things go bump in the night or day.

## Questions & Answers

**Q: Do they last 7 years and what would be some good spark plug wires to go with these sparkplugs i drive a 96 mercury grand marquis gs**
A: If you apply an anti-sieze compound to the threads of the spark plugs,prior,to installation you might,get away with leaving,them in for 7,years. Personally, I have not,gone,past 5 years with a spark plug before removing,it and replacing,it.

**Q: I need 6 that will fit 2005 ford escape, can you sell 6 i only see pack of 4**
A: No

**Q: Will these plugs fit a 02 mazda b3000 v6**
A: Yes they will

**Q: What's the difference between 9605 and 9608 Bosch iridium spark plug**
A: The 9605 and the 9608 are exactly the same in features and construction -- they are made to "fit" different vehicles, depending on heat-range requirements.
 The 9605 fits my 1995-1997 4.6 L - 2v FOMOCO engine.
 The 9608 fits other vehicles -- Chrysler, Ford, Dodge, etc. 
 Always check the Vehicle Compatibility Chart before ordering.
