Owner reviews for spark plug

kinda smoothed out the car a bit, idles smoother as well.

Finished up another swap over the weekend. Runs great. Gapped a new set of BKR5E's to .032" and put them in a buddy's daily driven B4 VR6.

The coils I replaced with oem and the spark plugs Denso IKH24.

Also, did you even replace the spark plugs with Denso IKH24's? Probably not and that is REQUIRED in order to run correctly.

On 02/18/2016 I switched the plugs with the Denso IKH22 at 15800miles. Jetta is more rev happy. No slow down throughout rev range, and no more pause hesitation between 3.8k-4k RPM. Just pulls, and pulls even harder. Also idle very smoothly.

Replace those plugs with nothing other than the Champion 7989 plugs. They are about $14 each and they are a 1 piece design.

I actually have those exact plugs in mine for about 10K miles now and have not hat any problems.

I got misfires with FD5POR RS2 plugs. Almost 10000kms on Bosch f2cs this year. Been working perfect for me

Worst case of electrode wear I've seen was on a set of Bosch 3-electrode plugs in a VR6. Plugs were so far gone, that five of six had triangular shaped center electrodes. Really thought I was gonna gall the head threads they'd been in so long.

Went through both ngk and autolite, didnt like they're spec'd plug for it.
