Spark Plugs for Lancia Fulvia's engines
NGK spark plugs outperform Champion in quality and reliability.
We suggest the use of BP7ES plugs for 818.302 and 818.303 enginese, whereas colder BP8ES are neccessary for 818.342 engines.
NGK suggests the use of D8EA plugs for 818.540 engines which should be comparable with DOES. As said before, it may be a good choiche to use colder D9ES if the engine is worked hard in summer. Despite of the low price, D8EA give haigh performance.
Race tuned engines
If tha car is mildly used (meetings and occasional runs), we suggest NGK B8EV for 1,3 engines and D8EV for 818.540 enfgine: uit is an extremely refined spark plug with gold-palladium centre electrode, quite difficult to procure in 818.540 version, it is common for 1,3 engines. Expensive, but with a remarkably long life, it is in our opinion one of the best spark plugs that may be used on a Fulvia. With the B8EV fitted on the Gr.4 Fanalone (equippd with a spacial cylinder head that used 14mm thread plugs) Fiorio/Stella raced twice Montecarlo HIstorique Rallye flawlessly. Even better may result the B8EG.
Champion A 59 C Racing. For .540 engines tuned at top level of performance and perfectly efficent, expensive but give exhilarating performances.
Champion C 57 Racing. For 1,3 engines tuned at top level of performance and perfectly efficent.
NGK B95EGV Racing. For 1,3 engines tuned at top level of performance and perfectly efficent, it is without doubt the best racing spark plug. Unfortunately D95EGV for 1,6 engines seems not to be available.
The Rallye 1,6 HF 001006 owned by Carlo HF Stella runs with DPR9EA-9, showing excellent performance. The last plug's code figure maens a .9 mm gap, gap that should be carefully checked and adjusted to keep top performance.
