Owner reviews for spark plug

OEM plugs which are NGK BKR5EKU used to get 26-28mpg @ 192k miles

after you get everything fixed don't run the oem plugs, they are too hot, if you want to run iridiums then get plugs that are 2 heat ranges colder and you'll be better off. you can also run copper plugs, i run ngk coppers that are 2 heat ranges colder and have had no issues at all.

I got... bosch platinum plus plugs... and you could feel the difference right away with the new plugs. started faster, idled smoother

I replaced my plugs with NGKs about 10k miles ago, I got them on amazon for about $12 a plug I think, engine runs great with them.

NGK BKR5E... Dual or single electrode, they both work well. These are the best plugs for these motors imo. They’re some of the cheapest as well.

I just installed STI plug wires and NGK spark plugs. After the install the car tried hard to turn over again but still gave me the same issue as before. Turns out the motor was not getting gas so I didn't need to get new plugs/wires, but I am glad I did because now my car doesn't idle weird anymore.

Car's is running smooth with the new wires and NGK spark plugs.

I am at 20,000 miles with my 07 VW GTI that has several modifications including a chip and I am about to change my spark plugs. I have heard many people say that the colder application spark plugs will work better for my car due to the fact that it is chipped. I went to the dealer and purchased the bosch #101-905-631-B spark plugs which the dealer recommends, but I dont know if these plugs are the colder application? Please give me your guys feedback on what plugs I should buy (Part #'s and website that I can purchase them from). I care about my GTI and want it to run the best it possibly can. I appreciate any feedback you guys can give!

All the recommended denso plugs have the wrong gap. They list 1.1mm gap for the 2.0t The recommended gap should be .7 to .8 mm Plus the "20" heat range misfired a lot in the cold for me (about 20 deg F)

econolines are ok except for one huge cluster****. On the late 90s through 02 i think they built them with too few threads on the heads for the spark plugs. Consequently spark plugs routinely blow out.
