The 9 heat range plug the R35s use is a NGK 22401-RS080-09 (Also known as NGK R2558E-9) but stock DILKAR plugs are 12mmx19mm and that plug I listed is 12mmx26.5mm.so it is a long reach plug and may not work.
Heat range looks ok. Hard to tell on the timing mark on the ground strap but 1 pick shows it at the bend so that's good. Rich idle and a couple look slightly lean at WOT. Overall not bad. I'd want to richen it up a bit at WOT and lean out idle.
Thanks Spider. I’m planning on getting an ECUtek remote tune soon (which is the reason why I changed the spark plugs). I’ll share your information and my spark plug photos with my tuner - although I’m pretty sure he’d be able to figure out how my car runs when I send him some data logs.
For s**ts and giggles, I looked at RockAuto for the NGK (OEM) Spark Plugs, and came across this info (in bold):
Laser Iridium® spark plugs provide superior ignitability and long service life. Smallest tip diameter available Iridium / Platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions
Laser welded Iridium center electrode tip
Platinum disc welded to backside of ground electrode provides long life
Trivalent Metal Plating for superior anti-corrosion and anti-seizing
Tapered ground electrode to minimize quenching
Consistent and stable spark
Faster starts and quicker acceleration
Better fuel economy and lower emissions
By inspection, this would imply adding anti-seize paste to the spark plug threads is not required.
For those wanting to buy the NGK OEM Spark Plug, DILKAR8K8G, Napa Auto Parts is having a 25% discount when you buy three (3) + items. Before the discount, the plugs are $19.49 each. After the discount, $14.62 each.
I kept getting P0300 codes. First couple were few and far between at ~28K. at 32K P0300 was more frequent and finally cylinder 2 just stopped firing all together. Put in Brisk plugs but I dont like them, low/mid throttle response is muted compared to stock. Just bought the OEM NGK to put back in there. So yeah not sure what these oem plugs are rated for, but mine lasted about 28K. Anecdote learned I'd prob plan to replace them every 20K.
hi guys, So the other day I noticed that the wires leading into the connectors for the MAF sensors were dried and cracked right at the base of the connector. I ordered new connectors and they showed up today. I took pictures of the wires before so I knew which wire connected to the corresponding...
So I just picked up a 2016 red sport this weekend. My second Q50, first red sport. Blast to drive, but as I started getting a little more familiar with the car, I noticed something...
My exhaust tips look like a regular old q50, all the other red sports I see have the tips with the circles...
Am I the only person with a Q50 with broken air cleaners? Didn't get the car new, but I'm guessing the folks at the quick change oil places are simply not qualified to check an air filter without breaking everything they touch. sigh.
I've got breakage on all four of the parts left / right...
Since the update last year I continue to have sensor problems with my Q50 2019. When I bring it to the dealership they say they can’t find the problem. I even brought it in with the warning dash lights on and they said they can’t find an error. Also the braking or the push against acceleration...
Been poking around the internet on tuning kit for my 2015 Q50s hybrid. Found nothing, so figured I post it here to see if anyone know. I already and exhaust and cold air intake.
Thanks in advance.
