NGK TR55 plugs
 

I'm not to familiar with NGK plugs but my quesiton is, on eBay I see the TR55 plugs at different pricing for different cars, eg. Camaro, Vette, Firebird, Mustang, Silverado etc. at diffenent pricing but same quantity from the same seller. Does this make sense?

It could make sense if the Vendor is trying to make money.

Whatever the market will bear......so buyer beware.

some people just wanna make a buck on ebay :roll:

Sorry if I'm off topic, but I'm getting ready to change the plugs in my L27 soon: I've been running the TR55s and have no complaints, but am wondering if I shouldn't try some Platinum plugs this time around.....Since I'm not SC'd I don't see why [other than cost] I shouldn't try them: any thoughts/comments?

It depends... I have Rapidfire 14 Platinums in my 95 SE right now... I will be pulling those for the TR55's.... I liked the way the car ran with the TR55's... And was somewhat dissappointed with the Rapidfire 14's... But never got around to replacing them... I have TR55's in the 91 LE bonneville as well and love them... I'd say Platinum or not is up to you... They do tend to last longer than a standard plug, but I pretty much never leave a set in that long anyhow...

For you guys wanting the TR55 for the 3800, the stock number is 3951

I ended up buying the TR55 Online at Sparkplugs .com for 2.24 each. One of the reason was due to the reasonable shipping charges to Canada.

Which car is it going into??

Ensure not to use Platinum for your boosted car.

Copper or Iridium for boosted car. ( I'm runnin Iridium.. and so far so good.. knock on wood.. )

Frank... :bsmack:

Locally...they are much cheaper and you know the shipping situation...

It's the same as I have in the 95 SSEi, this is a spare set so I can take advantage of the shiipping. I checked my reciept and it just says NGK V-power spark plug.

When you say locally, do you mean local to you? Do you think 2.24 each is a bit pricey? And thanks for the shipping situation Bill, I only use that as a last resort. I order stuff every week. You should see the list of stuff I ordered for Cath's car...

Thanks Merdock and Bill........by the way Merdock.......nice to see you back on the forum and you did have some good advice after all.

Ok, Looking to upgrade the sparkplugs and was reading though this thread.

Accordingly, I need iridium for my SSEi, correct?

http://www.ngk.com/results_app.asp?aaia=1247442

According to that, they should be $6.95 each for the NGK TR55IX gapped at .060. I would want to get these and regap them to .055, correct? Thanks.

I've got a 95 SSEi and only put the V-power spark plug, not the iridium, mind you I only drive it around the block once a week for the last several months.

Can someone shed some light on this subject?

Bill is right, just about any local autoparts store will carry them. So save yourself the money and check a store buy you.

NEVER use platinum in a SC, Turbo, or Nitrous application.

Standard V-Powers are copper plugs and are preferred. Irridium's should also be just fine for SC (not suggested for well modified cars, as you'll be changing plugs often enough to not want to pay for Irridiums twice a year or more).

Copper, Platinum, or Irridium are fine for all non-supercharged. Copper V-power's should run you about $1.50 a plug MAXIMUM.

So I guess the question is [since I don't mind paying for the Platinum plugs if the answer is yes], would I actually see any gain [be it performance/whatever] for my L27 over the TR55s I'm currently running?...Winter is just around the corner [well, not really, but I'm due for a new set o' plugs] & I'm willing to spring for the added cost if it's worth it...

Thanks again Will, for that bit of info, as for the $1.50 a plug, not the case with me. I had posted awhile bad asking for recomendations on suppliers of spark plugs and it was suggested to purchase from sparkplugs.com. There V-power spark plug is $2.25 each. I ended up purchasing a spare set. Oh well, live and learn.

Spark plugs are not power-adders. They're replacement tune-up parts. However, in the case of the V-powers, you MIGHT notice it. They tend to deliver a slightly smoother idle due to the design.

I prefer them because of the dual-spark path. Slightly smaller odds of blowing out the spark under high boost.

That's somewhat misleading. They're no good in our applications, but they came OE in 3.8 SC fords. They might run @ different temps, or require different ranged plugs. I think most people modding them keep the same style as well from what i've been told.

THat being said I :heart: my TR-55 v powers..

X2 they are great in the L27

and mine are even better cause they came out of a L67

NGK specifically states NOT to use Platinum plugs in ANY forced-induction application, period. NGK also manufactures the OEM AC Delco plugs.

I'll take that as gospel, Jason. Thanks just the same.

Just passing on what the Fordies told me. By no means am i suggesting anyone put a plat in any 3800. I don't see the point as they should be changed out more often then 100k. For the cost why not have piece of mind.

I can honestly say, i have had three SSEis, on third one now...i used Bosch in my first one the first tune up ever, they died after a few months..AC delco OEMs seems to work REALLY well, but the VPower Tr55s i get at a better price, and seem to last much longer in a boosted car, copper is old technology, but its GREAT for the high performance market. I dont even look at another plug when i get them for my cars, its ALWAYS the TR55 8)

I know they made my tired old L27 run allot better! Great plugs at a great price IMO.

On a quick note, the best plugs are the Silverstone spark plugs on the market made by Nology, due to Silver is the best metal for conducting electricity. I have found more power with these sparkplugs then any I have tried. I have tested about every spark plug there is on the market and the best one I have come up and are using at this time is the Nology Silverstone sparkplugs and is very noticable. The others such as Iridium and the copper are good but really unnoticable in performance. Here is Nology's website and see if you like them. Its really in preference but I do notice a big difference. http://www.nology.com/silver.html

So, what sort of distance are you guys getting out of the standard Tr55 V-powers. I love NGK and I've been using them in all of the family's various vehicles (several 4 and 6 Nissans, a Caravan, an ancient volvo, etc) since forever and they've never let me down.

I'm willing to fork out the cash for the IX iridium NGKs if it means I don't have to change them for 100k miles. How many miles are you guys managing to put on the standard TR55s before they need changing? For reference, my car is a non-supercharged Series II '95 Bonneville.

I think the most I put on a set was 20k+, and they came out looking great.... But I'm a stickler about having fresh plugs...

cough Cough...wow...dusty old thread there.

Mileage will vary with driving conditions/abuse etc. it's tough to say...however I'd expect 20-40 with care.
