Bosch FR7SPP302U - Spark Plugs Platinum - 1 piece

I did't have a chance to install them yet but i'm using the same (platinum type) for 7 years now.

The Bosch #9605 is a DOUBLE IRIDIUM design, which uses an Iridium coating on BOTH electrodes. Another Amazon 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 Amazon) 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.

Excellent, I put them in my car and you really feel the difference... I recommend them...

Only spark plugs that gives my Acura or Honda noticable power improvement. Vehicles feels more powered and smoother.
