Bawwxay Member 50 Member For: 1y 8m 14d Posted 14/07/22 08:25 AM Share Posted 14/07/22 08:25 AM G’day everyone, first poster here. just thought I would make a post to get some more information regarding spark plug replacement. I recently turboed a 2004 NA BA Barra 182 and was curious as I’m about to replace the spark plugs whether I should stick with NA spark plugs (NGK FR5EI-13 Iridium) or go with the 240t spark plugs (NGK FR6EI-11 Iridium)? Obviously the gapping would be different on the two and whether the 240T plugs will even fit/be a more viable option? Link to comment Share on other sites More sharing options...

They're stock gas plugs. Link to comment Share on other sites More sharing options...

These are what you want:https://www.ebay.com.au/itm/200973896683?mkcid=16&mkevt=1&mkrid=705-154756-20017-0&ssspo=8S9VA-FsSJ2&sssrc=2349624&ssuid=N4BYE3kzRYW&var=&widget_ver=artemis&media=COPYEdit: posted same time as Keith's second post, but same same 1 1 Link to comment Share on other sites More sharing options...

BKR7E will work. Gapped to 0.8mm. That's what mine runs. Have used the gas plugs too, they were good Edited 14/07/22 10:26 AM by Tom Tucker Link to comment Share on other sites More sharing options...

Here's a video that discusses some of the difference, wait around until you see the plugs firing with the lights off. 1 Link to comment Share on other sites More sharing options...
Bawwxay Member 50 Member For: 1y 8m 14d Posted 14/07/22 10:42 AM Author Share Posted 14/07/22 10:42 AM (edited) That’s why I’m after some iridium plugs I just didn’t know which ones to get as it’s a turboed NA motor (silver top), would the NGK FR6E-11 be fine? They are the ones NGK say suit a red top. currently running 10psi on a gt3582 stock xr6 turbo ecu. heard 0.8mm is the gap to go, opinions on that also? Thanks for the replies so far 👍 Edited 14/07/22 10:45 AM by Bawwxay Add to post Link to comment Share on other sites More sharing options...

This is dependent on ignition timing as well but we don't need to worry about that for now. Just get the genuine Ford gas plugs and put them in. They are pre gapped to 0.7mm which will be fine. Use whichever ebay seller you prefer, the prices change here and there but should be around the $50 to $60 mark. 1 Link to comment Share on other sites More sharing options...
