Looking to replace the plugs and I get Bosch FR8DPP33+, 9600, and 9652. Which is best for a 6spd NA coupe in a hot climate please ? Is there a difference ? YWTK


ps 9600 seems to be a heat range 8, 9603 (mentioned in another post) is a 7 (colder). Is the 03 for a SRT ? These two are indium, DPP is dual platinum.


pps is one plug easy to get to to see what is in there ?

 

Don't know about the Bosch, Rob at Needswings has the NGK Irridium IX plugs in 2 heat ranges for $82.95 a set.
I put the normal range plugs in mine, no problems for 2 years now. Climate here about the same as yours.
The DS front plug is easy to access, if you are gonna replace all 12, then I'd recommend unplugging the coil packs and removing the valve covers.
Your hands will thank me, plus you can get a torque wrench on them. ( 21 ft/lbs )

 

Amazon is having a buy 3 get 4 sale on the Bosch 9600 and 9603s. I ordered 12 9600s for $54.90 from Amazon with free shipping ($58.50 with Fla tax).

 

Good buy. I'm sure they will work just as well as the NGK's.
