I'm trying to help a neighbor's kid by ordering four spark plugs for his
But where can I get a lookup table that lists all (or most) so that we can then go on Amazon to find the lowest price plug that simply fits the car?
Take a look at RockAuto at
Rock Auto is very reputable, etc
Just search any auto parts store and pick-your-price - .. the part numbers are shown - create your own cross-ref. chart in about 2 minutes with a pen & paper.
I doubt that you'll save much on amazon but I could be wrong. John T.
NGK DPR8EA-9 at Canadian Tire is $8.99
On Amazon they go for from $12.97 up - or if you need 4, $5.62 each in Pkg of 4.
The RJ12c is $4.99 at Canadian Tire and from $29 to $65 for 4, (about $7 to $16 each) or $16 each if purchased singly.
RL19LM is $4.99 at Canadian tire - $12.63 to $30.6 on Amazon.
There are lots of off brand "equivalents" for less - but still pretty much double the CanadianTire price - Oregon @ $9.54, Briggs at $11.93, Anxingo at $11.99 etc.
Amazon CAN be cheaper on some things - and ordering from them saves a trip into town - and in some cases they have something your local bricks and mortar shop does not have in stock - making them a good alternative.
Generally IF I can source locally I do - If I can't I go to Amazon. Sometimes brand doesn't matter - it might even be they have the "OEM"
-and sometimes at competetive price.
You must be careful buying auto parts on Amazon. There is an epidemic of counterfeit parts. Spark plugs and OEM filters are especially notorious for being fake Chinese ripoffs.
Almost any 5/8" spark plug will fit. Doesn't mean it's the right spark plug for your car in your environment.
Every size of spark plugs comes in a multiplicity of heat ranges. Plugs too cold ---> fouled cruddy plugs, incomplete combustion. Plugs too hot ---> burned electrodes, burned valves, piston damage.
The first thing you should have done was read your owner's manual and see what the mfr recommends for your climate. Manuals are available online.
RTFM before asking the ignoratti. I can't believe no one gave you a sensible answer.
That's why I buy most parts (cost is a factor ...) from Marty and his crew at my local O'Reilly Auto store . They all know me by name and are always helpful with me getting the best choice for my dollars . Often getting it today or tomorrow is worth a couple more bucks .
It's not "my" vehicle but I found out what's in the owners manual which says only these will work NGK BKR5E-11, Denso K16PR-U11, Champion RC10YC4.
But the kid asked me if any others will work & that's why I asked here to find a cross reference table that will tell me if these will work also.
Champion RC12YC5 - also known as #89 is the base plug. Likely the lowest cost "brand name" plug you will find for the car and good for about 1200 miles. If you are going to keep the car the more expensive versions could come out lower cost in the long run. At higher cost, irifiumand platinum 3071 and 7070
NGK 2382 or 6953 Denso K16RU11 or K20RU11 Delco FR3LS6
Best price will almost ALWAYS be at Rock Auto, particularly if you are in the USA. Walmart would be a close seconf, but you have SO MANY auto part places like PepBoys who also sell stuff CHEAP compared to here in Canada so it's hard for me to say.
Even here in Canada it is often REALLY HARD to beat Rock Auto's pricing, even counting in shipping on light stuff.
The counterfeit stuff is even finding it's way into "the channel". If I can't buy reasonably locally I am more likely to buy auto parts from Rock Auto than Amazon. Often less than half the price of local Canadian sources. Even a lot of the local channel stuff is offshore and not OEM for Japanese and Korean cars. And more than you would like to think of OEM parts - even assembled into your car at the factory in "american" brands - is Chinese or other Asian offshore manufactured.
I've known for a long time about "offshore" parts in American brands . Both of my Harleys have Showa front forks ... and so did my '88 Sportster , it's been going on longer than most realize . I'm pretty sure most (original) if not all of my '99 4Runner parts were made in Japan ... it's probably 5-7% Chink by now , but nothing that can spy on me and report back to the CCP <bwahahaha> .
Point taken. Please forgive me for being harsh with you.
total unknown quality / manufacturer. Your old ones may well be better - - - -
If iridium is good, double iridium must be twice as good, right?
As for the x-ref, I don't think they exist.
What you find is Champion will have their own x-ref to their plugs. Then Bosch will have their own proprietary x-ref to their plugs. NGK will have their own proprietary x-ref to their plugs too.
But there is no master cross reference out there. That would be exactly what everyone would want. So it doesn't exist.
Impressive prices at rock auto ! Thanks for the tip. Just as a test, I priced 4 NKG spark plugs for my last car - a Kia Rondo - $ 20. each at my local Canadian Tire ; $ 13.45 at Rock Auto but $ 20. shipping to Canada .. .. still a little cheaper but not a big deal. $ 28. was the cheapest I found on amazon ca when buying 4.

Single platinum or single iridium plugs work just fine for COP or CNP ignitions, as well as distributor ignitionds. Double plat or double iridium are ONLY beneficial with lost spark, or "dual polarity" ignitions where the spark may fire from center to ground, or ground to center. THAT is what dual plats were designed for, and the only place they are "better" than single plats - but because of the price of Platinum (or iridium) they ARE more expensive - better or not. As for cross references, unless you are using adatabase program a REAL crossreference is pretty much impossible - but NGK or Champion or Bosch or Delco or whoever have pretty good crossreferences from THEIR p[roduct to pretty much all the "big brands" and if you know how touse them they tell you pretty much all you need. Now if you want to use some add-ball crap like "splitfire" you need to use THEIR cross reference.
Back in the day when part numbers MEANT something it was easier. Every number or letter in a Champion or NGK or Nippondenso plug meant somethint, so RJ12yc or rc12yc told you what size and length of thread, what heat range, the material of the core, whether resistor or not - etc. Forinstance the only difference between the 2 I mention is the length of the thread, and if you want a hotter plug you go to a 13 or 14 or 15.
On Nippondenso plugs the heat range went the other way, with a 16 being hotter than a 20.. Now with numeric numbers like an 89, 3071, or 7070 it doesn't tell you SQUAT (all 3 are the same physical sixe and length of thread, same heat range, and will fit the same applications - but ONE of them is good for double polarity ignition
When ordering from Rock they ship from numerous warehouses. If you order the plugs, and a PCV valve, and a rocker gasket and a few other small items that ship from the dame warehouse your shipping may only go up a dollar --- but 2 items from different warehouses could double your shipping. There is a little truck icon that indicated what ships from the same warehouse as your first item and sometimes you need to play around a bit to get the best dealm shipping included - possibly by buying something a bit more expensive to optimize shipping. Also taking a shipping option that takes a day longer can make a SIGNIFICANT difference. I NEVER use UPS. Generally Purolator or US POst is cheapest and best service.
That was what my observation is, which is that Brand X will have a cross reference specific only for Brand X spark plugs.
That is, there is no "real" cross reference that I know of for spark plugs.
What I find strange is that this one thing everyone wants, doesn't exist.
All I can find are companies claiming that a given list of other spark plug model numbers fits their particular spark plug brand and model number.
If you know how to read the bloody thing - like reverse cross reference, it is a cross reference for every brand it cross references to. How do you propose, on a sheet of paper, to cross reference from every brand to every brand of every one of, possibly 300? different plugs Champion makes? It would be fun in a relational database - not so much in a flat-file or spreadsheet.
That's a cross reference. There are cross references limitted to 2 brands - like Champion / NGK - but also Champion to NGK, Bosch. NipponDenso, AC Delco, Autolite, Motorcraft, and others. You look at the column for the one you know, find the part number, and read across the row to the column of the brand you want to use, andread the part number. If you want to sort them by the cheapest plug that matches that you can buy in Lower East Podunk Alabama? Good luck!!
Using this wonderful new technology known as The Internet - you can create your own cross ref. chart in a few minutes with a pencil & paper. Search for your car's plugs on a good parts site ; write down the mfg. number and price for the dozen or so choices that appear. It'll take a little longer for your vintage lawn mowers and chainsaws and such - so be sure to write down and save those ones, once you've found them. John T.
