Spark plug equivalent - Ngk Lfr5A 11 Spark Plug

i cross referenced the spark plug (LD A7RTC)
and got the NGK equivalent:

SKU: #CR7HS
ITEM : # NGK7223
BRAND : NGK
Then got the specs off the NGK site

NGK 7223 CR7HS Nickel Spark Plug

It should be a 5/8" (16mm) spark plug socket.

If you type this question into google you will get several equivalents. You may find questions like this are more quickly answered using google rather than waiting for Fixya answers

Spark plug gap, .051 or
1.3--1.4mm
That is for motorcraft spark plug, AGSF-32WM or equivalent.
Different spark plug manufacturers may have different gap specs.

NGK B6ES = Champion N5

Spark plug cross reference

This would equivalent to OEM
Iridium spark plug
Bosch part #9614 around 6.99 each

You can run other Bosch plugs from copper and up but you car calls for the iridium plugs hope this helps..

You either have an incomplete number for your AC spark plug or it is a very old, unusual or obsolete type because there are no equivalents for that number.

I suggest instead of trying to find an equivalent you should use the make and model number of your appliance and buy the recommended spark plug from the application catalogue of your choice. I am not fond of Champion plugs for no particular reason and prefer NGK.

Two plugs mentioned here.

FR7DP, 4228 and Spark plugs: Champion RC8PYP 8 (or equivalent)
Spark plug gap: 0.028-0.032" (0.7-0.8 mm)

From
http://new.volvocars.com/ownersdocs/2004/2004_XC70/04xc70_09.htm#pg149
and
http://www.thevolvoforums.com/volvo-c70/12090-c70-spark-plugs.html

The earlier 1999 Discovery uses NGK BKR6E plugs or equivalent and the gap is 0.8 mm (0.025"). The later 1999 Discover uses NGK PFR6N-11 plugs or equivalent and the gap there is 1.1 mm (0.043")

You need to use an NGK 7092 Spark plug or equivalent. Note this is a NAPA part number & may not work everywhere.
So to answer your question, No you can't use just any plug.

Spark plugs: BPR6ES (NGK), W20EPR-U (DENSO). You cna cross ref any other equivalent with a spark plug cross ref book.

Thanks for choosing Fixya.
