Re: Spark plugs! Do you agree on this?

[tommy1982]

Im having a problem with my car. Every morning or kapag malamig pa yung engine napansin ko pag papaandarin ko na ang hirap or hindi maganda yung timplahan ng clutch and gas. Parang mag jejerk ng konti yung andar at parang mamatayan ka ng engine. Sa 1st gear ko lang naeexperience yan. Kapapalit ko lang ng sparkplugs... possible kaya na hindi compatible yung sparkplugs sa auto ko? My car is a 2004 rav4.
Someone told me na baka daw cold sparkplugs nabili ko... Meron ba talagang cold sparkplugs? Need pa daw painitin ng konti bago mo paandarin yung auto... Any suggestions kung anong magandang sparkplugs babagay sa rav4?Im using bosch platinum right now... I know maganda yung mga iridium,kaso namamahalan naman ako masyado... Please help. Share your comments friends! Thanks!

check your car's users manual for the recommended spark plug. OEM plugs are still the best IMO.

It's also a good practice to warm up your engine before driving to let the oil circulate your engine.

Hot and Cold Spark Plug

It refers to the heat range of the plug as related to the original manufacturers recommended plug.

A hotter plug actuall means it will stay hotter in the cylinder (colder, just the opposite). By the base thickness and porcelain sizing, this temperature can be varied. By examining the plugs, you can determine whether the plug temperature needs to be varied to allow for a better burn at the plug.

How spot those plug?

A long center electrode is a hot plug. It's how fast the center electrode conducts heat to the head. Short center electrode = cold plug. If you put too hot a plug in, it will cause pre-ignition. You can get colder plugs if you get pinging after the car warms up. Most motor boats run very cold plugs. The heat range for a spark plug just gets the center electrode hot enough to burn off any buildup. If you put too cold a plug in, it can get buildup and you have plugs foul up. Lots of short trips could use a plug one step hotter. Long highway driving could use a plug one step colder. But with modern electronic engine controls, you probably don't need to change from the stock heat range. Go back as it was that recommended by Toyota.

Visit a plug manufacturers site or your car manual for your vehicle, they will explain the plugs, and usually any potential recommendations for plug selections.

Lastly, if you search the web knowledge forums for your type of vehicle or engine, you can usually find others that have done the homework for you, you just change to the plug the forum recommends.

Hope this one help.

platinum plugs are good but look for the actual equivalent of your oem to prevent problems. you can always ask casa's parts advisor then buy outside to get it cheaper.

you can check www.sparkplugs.com to see the equivalent of your oem plugs to other brands and performance plugs

Early this morning i tried heating up the engine first for about 5-8 mins before driving it. Meron padin nginig sa engine habang slowly mo paaandarin... tsk! Pumunta agad ako sa petron to buy the stock sparkplugs sana,kaso nung pinatest drive ko sa "headmechanic" nila,sabi naman nya sa clutch daw yung problem. So,naguluhan na ako,i end up going home na hindi na muna ako bumili ulit ng sparkplugs. Pero on my way home,naging normal naman na ulit yung timplahan sa 1st gear,nawala na yung nginig. Defenitely hindi naman siguro nag kukulang ng gas distribution so no need para ipa check ko pa yung fuel pump... Thank you sa mga naunang nag comment.I hope matulungnan nyo pa ako...

mababa ba yung idling pag bagong start? pwede mo ipacheck yung IACV baka cleaning lang din and I agree sa na OEM sparkplugs are still the best kaysa sa mga aftermarket at mamahaling sparkplugs.

[Mile2]

Mura lang naman ang stock Denso spark plugs sa Toyota Dealers.

The last time I bought a stock plugs for Innova cost P81/piece, it would probably be the same price range for RAV4, and you will certainly get genuine parts and don't get faked products buying from auto supply.

[Galactus]

Maybe its the platinum plugs nga. Am also using one on my 97 Accord, at hindi maganda ang idling. Very rough. Pinagtiya-tiyagaan ko lang, kasi nanghihinayang ako sa presyo. This never happened when I was using stock plugs.

Pag di ko na natiis, balik ako sa stock. Mura na, dependable pa.

[ramledi]

try regapping your plugs it might work

hope this site would provide yous some info regarding cold and hot plugs. it will also explain what type of plug is better for your vehicle. cold plugs is usually use for vehicle the travels long since engine runs hot for a long period of time it needs to cool fast. hot plugs usually use by vehicles that travels less like home-office and office-home. you can determine if the plugs are hot or cold by the numbers indicated on the part number of the plugs for NGK lower number like 6, 7 are hot plugs and 8,9,10 are cold plugs. for denso 11 to 18 are hot plugs 20 above are cold plugs.

So,do i still need to make the engine a liltle hot before driving it if im using the cold spark plugs? o sa hot plug ko gagawin yun? Sorry,im confused...
Oo nga pala,today ok yung andar nya. Walang nginig sa 1st gear. Im still using the same spark plugs(bosch platinum).

Do you guys observe kung ilan ang rpm nyo sa 100kmh? Mine is at 2,500...

What is the number that indicates your sparkplug number is hot or cold plugs. if your plug is a cold plug and your engine doesnt run for long period of time it will not get the right operating temperature immediately. hot plugs easily gets its operating temperature even with a short period of time.

[aejhayl17]

eto solusyon if i were in your position...

check if may hangin sa clutch and brake lines, if meron, bleed lang yan then refill. di pa ba sliding ang clutch mu?

change your platinum SP to stock, if andun pa din problem mo, check mu yung engine idling, kung mababa agad kahit kakastart mu pa lang ng makina(morning cold start), pacheck mo na sa mekaniko. i recommend NGK sparkplugs, it is the alternative SP for denso , and also used by toyota itself.imho bosch sucks! busina lang ok sa kanila

when ka huling nag change ng transimission oil? i assume na manual ka, so baka due na for pms ang gear oil mo.

and lastly, anung viscosity nilagay mu nung nagpachange oil ka? baka its too heavy kaya medyo hirap makina mo.

try to reset your ecu also, tanggal ka lang battery for `10mins. then start without revving it.

[ramledi]

kung lumitaw ang problem mo after installing the platinum plugs then just get the oem plugs then see if it will solve your problem. oem plugs are cheep naman

Ok naman idling ko,pag sa morning above 1k,then after a few mins bababana sya. ito mga previous upgrades ko sa auto,Palit mags(16s-19s, Palit air filter KNN, Palit na din fuel filter, Spark plugs. Its been 3 days since nag post ako dito,as of today ok na yung andar nya,wala nang nginig. Take note,yung bosch padin na SP ang gamit ko ha... So ano kaya nangyari nung mga araw na may nginig kada malamig yung engine???

Nag iba din FC ko,from10km/lit city naging 8.3-8.8 km/lit nalang... Malaki kaya naging part nung mags ko sa naging difference ng FC ko? May nakita akong thread dito talking about KNN. May mga nag comment na nung nag palit sila ng KNN filter nag bago FC nila... Akala ko ba more HP plus better FC yung ibibigay ng KNN???

its a good thing your engine idle is ok now without doing any replacing again.probobly the fuel filter also contributes to your engine rough idle, it might cause some restriction so the engine hesistates. well regarding the fuel consumption, the big wheels has a big effect even though you have upgraded your air filter to a high flow KNN. more power means more fuel to burn to equal to the power. at the same time big wheels are hard to rotate than smaller one. big wheels will only benifit you on long travels because you will only need fewer rpms to reach your desire speed compare to smaller wheels. so on city driving you'll find it that thers a little higher rpm to move from stand still compare to the previous wheels.

did you maintain 10km/l FC while wearing those 19" shoes o after mu magpalit?

aftermarket or "racing" filters can provide better FC versus stock but with the right driving attitude and behavior of the driver itself. why? eh kung galit ka ba naman sa pagtapak sa gas pedal, e malamang malasing mu makina mu at parang umiihi lang ng gasolina eh.

di porket nagpalit ka ng free flow intake eh mas matipid na, depende pa rin yan sa nagmamaneho.

Moderate naman yung tapak ko sa gas,i always maintain 2k rpm before shifting gears. Minsan lang sa 3k,usually sa 1st and 2nd gear lang ako umaabot sa 3k rpm.

[tommy1982]

Since upgrading with 19s my Fc went down to 9km/lit.then after the knn now its down to 8.something... Nung pagka kabit na pagka kabit nung knn ramdam ko talaga ung nadagdag na power. Pero ngaun,its been 2weeks parang feeling ko hindi ko na maramdaman ung nafeel ko na improvement nung bagong kabit sya... Hindi ko sure kung baka na imune lang ako sa performance na with the knn or baka meron talaga akong kaylangan ipaayos or ibalik nalang either ung stock filter or pati na ung sparkplugs...

[p_borj]

parehas tayo na na-immune na pati yung bumaba ang FC nung nagpakabit ng K&N air filter hehe.
