Owner reviews for spark plug

No issues with Bosch red coils from Shopdap Bosch Red R8 Ignition Coil for VW Audi 06E905115F - Deutsche Auto Parts (shopdap.com) Spark plugs: NGK Ruthenium HX, #92400.

Got some NGK Ruthenium HX plugs at NAPA this morning. Miss is gone, car runs perfectly again. Plus they're cheaper and supposedly will last longer than the platinums.

Thought I would follow up on this discussion. Ordered the NGK LFER7BHX Ruthenium HX. The priority package showed up after some challenges with the local Postal Service. As advised, on Tuesday took the car for a short drive to warm it up then started the task. Was a little pensive taking the engine cover off. To anyone who has never done it on that particular car, just pull each corner straight up about an inch and it comes right off. The cover is held on with posts that fit into rubber grommets so the chance of breaking anything is almost zero. Found a very old 10-14mm open end from the tool kit from a long gone motorcycle in the junk drawer, A few minutes with the belt grinder and a "perfect width for the ground bolt" 10mm open end was discovered hidden inside. The only real challenge is disconnecting the wiring loom from the coil packs. Several iterations of 'watch a video, give it a try, watch a different video, give it a try ...' ensued but I was finally able to get them disconnected. Gently removed the coil packs and one-by-one removed the plug, installed a new one, torque to 30Nm, wash-rinse-repeat. Put a little dielectric grease into the plug boot of the coil pack and the coil pack\\wiring loom connector, a little SYL-Glyde Silicone Grease on the large coil pack to engine seal and reinstalled the coil packs. Torqued the ground bolts to 12Nm, then put on the ground strap and torqued the nut to 12Nm while holding the bolt steady with the afore mentioned "super wrench". Fought with the wiring loom to get it back on all the coil packs, popped the engine cover back on and Bob's you uncle. Drive to the dealer Wednesday morning and went in to talk to the Service Writer. Mentioned that they did not have to rotate the tires (had already put the X-Ice tires on two weeks earlier) nor change the plugs as I had done that the day before. He gave me a strange look and said "Yes, VW recommends they be changed but with only 15,000 miles on the car I would not have bothered". Doh!!! Primary lesson learned here is "Call and schedule service yourself rather than let your wife do it." That way you can challenge the items on the "what will you be doing at this service" before spending an afternoon under the hood. (Side note, it is 'her' car as 'my' car is the FRS, hence her desire to schedule the maintenance.) They did the usual "full inspection" on the car and came back with "the rear brake pads are down to 3mm and should be replaced". They had photos to "prove" the pads were down to 3mm. I though this was strange and will be starting another thread to go over that discussion with the Service Writer.

I use NGK Iridium. They seem to burn a little cleaner than some other plugs I’ve used in the past.

I've decided to install the plugs myself. Given that the vehicle has nothing in the way of a tune, it would seem that the 'standard' heat range plug would be the best fit. APR does not seem to offer a 'standard' heat range plug so they are off the table. The prices for the NGK plugs from the dealer seem reasonable even there challenge is 'which one?' They list a 06K905601B Type 1 and a 06K905601L Type 2. Google searches offer nothing in the way of information about the difference. Is it the heat range? the external construction? the internal construction? the ???. There is a price difference in that the Type 2 is over twice the price of the Type 1 so I am assuming there is some difference, but no specifications to suggest what. To ensure theMuffinMan understands what I am saying ... I am not sensitive to the price difference BUT it is the only factual piece of information I've been able to find, other that part number, to distinguish one from the other. I am stating the difference as a fact and not as part of the selection criteria. Looking at the NGK offerings, they seem to be NGK PLFER7A8EG Laser Platinum or NGK LFER7BHX Ruthenium HX. Any insight would be appreciated.

For the last twenty or so years I have only used Bosch plugs. I have had great service in my VWs, Toyotas and Ford.

APR Z1003100 APR Iridium Pro Spark Plugs - 14x26.5x16mm - Heat Range 9 APR Iridium Pro Spark Plugs are the excellent upgrade for tuned engines. Our spark plugs are made from Iridium, which is one of the strongest materials you can use in this type of application. They run cooler, resist preignition, last longer than other materials with higher melting points, and... www.goapr.com

This. I had the 7s in previously. I swapped to the 8s when someone mentioned they got better fuel mileage with them I didn't notice any difference.

the autolites are bottom of the barrel, i've only used them once when i was young and dumb and ofc they busted while trying to repair and remove after.

Yeah, get rid of those: autolite is junk.
