Product Description
Bosch Platinum+4 has the most platinum in the Bosch Platinum plug series.ááPlatinum +4 unique firing technology combines the advantages of surface air gap technology and 4 yttrium enhanced ground electrodes.áThe fine wire platinum center electrode (which isáheat fused into the extended ceramic insulator) reducesáthe voltageánecessary to jump the gap as well as reduces quenching.ááTheá4 ground electrode design not only provides multiple radial spark pathsábut also the surface air gap designácreates optimal exposure of the air/fuel mixture to the enhanced ignition spark. The yttrium-enhancement of the ground electrodes even further extends plug life.áAll Bosch Platinum series spark plugs are designed to reach self cleaning temperature faster for quicker starts, smoother acceleration and increased fuel efficiency.

I installed these spark plugs in 2001 Tundra and they improved the performance and gas mileage. Just ordered another set for my 2006 Tundra and will order a set for my 2002 Camary soon.

The Only Plugs I Use! February 6, 2010

I love these spark plugs, I've been using them since the product came out upwards of 8 years ago or so (give or take). The Bosch platinum 4 spark plugs are gap-less, so no messing around with gapping. The four prongs ensure a spark every time (no misfires) and allows the placement of the spark right out at the tip of the plug for better combustion, which also allows for longer plug life with reduced carbon deposition. I ran a set of these for 6 years and never once had a misfire. In fact, the only reason I decided to change them after 6 years was due to a leaky valve cover gasket that leaked around the plugs. Over all, great product, well worth the extra money, with a quality name you can trust - Bosch!

I installed these in my BMW airhead (chomehead) motorcycle.
They stopped the nasty surging I had been having. They are
well worth the extra few dollars!

 Only worked for 5 months... July 24, 2009

It only worked for couple of moths and it started giving me problems, my MDX started clinging when starting up, these spark plugs made me change a starter on a car because the car didn't start ones or twise. I also made sure that the battery was good. Just get OEM spark plugs if you don't want any trouble on a long run.
P.S
Onyl reason I gave it 2 starts is because it increased fuel efficiency just a little bit (and I'm guessing it's because that I had old spark plugs before.
