Spark Plugs

Im at 37,000 miles on my car and the dealer recommends changing spark plugs at 30,000. I went to Autozone and they said the spark plug my car needs are the NKG BKR5E-11. Are these the right plugs? If so how long until they need to be replaced? Also I was told that replacing the spark plugs were harder then it seems. Something about the ecu having to be reset to let the car know that new spark plugs were installed. I have a 2009 Hyundai Accent four door manual transmission.

I put in NGK Iridiums, don't remember the part number off hand. Replacing the spark plugs took all of 15 minutes, there is nothing special you have to do to the ECU.

Technically, no they are not the right plugs per Hyundai specs (but they're just one rung up the ladder from the OEM spec NGK.) However one member here did get hassled by their dealer for having them installed when they went in for warranty work...

BKR5ES-11 is the OEM plug but it is becoming very difficult to source locally, at least from my experience. The BKR5E-11 is the 'V-power' version of this plug, the main difference appears to be with the center electrode. None of the usual suspects (AZ, Advance) carry the BKR5ES-11 anymore, only the BKR5E-11 V-power plug. Finally after I decided to try a set of V-powers from AutoZone, I noticed O'Reilly does in fact still stock them..

I don't know how well the V-powers work, I went to install them and I found one of my plugs rusted, the spark plug tube and coil looked to have been marinating in something for a while. I abandoned the project and took the car to the dealer to have them investigate and replace the plugs while they were at it. They used BKR5ES-11's according to the paperwork (and after googling Hyundai's part number to see what it cross-references to.)

Don't worry about any fancy shenanigans with the computer. It's a fairly straightforward swap.

Substantial markup on these things at the dealer. I was billed $35 for the same set of plugs that were $7.96 back in 2010 (last time I changed them.)

Just installed a set of the NGK V power plugs in mine an hour ago . Remember to put some silver anti sieze on the new plug threads and get a tube of di-electric silicon grease and put a bit inside the lip of the plug boots as this keeps them from sticking to the spark plugs and also seals from moisture .

as far as I know sparks plugs are standard, just the quality is different from one to another.....I replaced my sparks last summer at 98,000 klics.....now I'm at 123,000 and I have a pack of NGK Iridium IX (39.00 x 4) waiting for a warm day to do the replacement.............
